Freelancing e recebimento de dinheiro do exterior

Bom dia, doutores. Preciso sanar algumas dúvidas relacionadas ao recebimento de dinheiro do exterior principalmente com relação aos impostos e custos em geral. Sem mais delongas, vamos lá.
tl;dr preciso sempre declarar todos os meus ganhos fora do Brasil mesmo na minha situação (vide abaixo)? Como amenizar isso?
Ou então prossiga para a seção "O problema" para ver a pergunta em detalhes.

A situação

Sendo bem direto, tenho 18 anos e recém sai do Ensino Médio, não trabalho, nunca trabalhei, não tenho cartão de crédito, só uma conta NuBank e não tenho qualquer renda. Minha família está passando por uns apertos e para amenizar pensei em ganhar uma grana sendo freelancer para aproveitar a alta do dólar e minha semi-fluência em inglês. O plano inicial era tirar uns 500 USD por mês, tem projeto que paga isso numa semana, mas estou atirando baixo em trabalhos de data entry e tradução que pagam bem menos. Com esse dinheiro já cambiado e depois de uns 3 meses juntando, eu manteria ele na minha conta NuBank e começaria a investir com renda fixa e variável, day trade, buy & hold, o que for necessário e seguindo as informações daqui e de outros fóruns. Sei que não faria muita grana agora mas a ideia era de começar cedo e ganhar experiência.

Freelancing

Estou usando o site freelancer.com (sim, eu sei da Workana e do 99freelas). Entrei num concurso e tenho grandes chances de ganhar 15 dólares canadenses que, no câmbio de hoje, dá uns 54 reais. Teria trabalhado bem mais e criado conta na Workana e em outros site se não fosse o meu problema a seguir.

Explicando

Pelo que entendi, toda transação do tipo envolve duas etapas:
  1. Receber e converter o dinheiro para o Real (seja por banco ou terceiros);
  2. Declarar os ganhos no imposto de renda.
1 - Nesse primeiro ponto é necessário saber de antemão que segundo decreto de lei recente, brasileiros NÃO podem manter dólar ou qualquer moeda estrangeira na sua conta bancária sem antes converter para real. Aliás, é por isso que o Paypal converte direto agora, sem nem perguntar, usando taxas absurdas.Essa conversão se dá pelo desconto de impostos. Você sempre sai perdendo. Portanto, a questão aqui é minimizar as perdas.
Pelas minhas pesquisas, bancos comuns cobram 20 USD fixos + taxas de IOF + Spread + qualquer outro imposto que der no cu deles, seja pra 10 dólares ou 1 milhão. Por isso, bancos não valem a pena nesse processo. A alternativa é usar outras empresas que fazem o serviço usando taxas menores. Pesquisando, encontrei uns dez sites que fazem isso, como o Remessa Online, PayPal, TransferWise, Banco Inter, Western Union, Husky, Payoneer, Skrill... A lista é longa e não é da intenção desse post desenvolver nos detalhes intrínsecos de cada um. A verdade é que o Remessa Online é o melhor de todos até agora pois para receber dinheiro de fora não há tarifas fixas como na maioria e o IOF é de apenas 0,38%, além de um custo de 1,3% do valor recebido, uma das menores que achei. Pra simplificar: no final de tudo seria descontado 1,68% do teu câmbio final (que tu receberia sem as tarifas), o que é bem conveniente para pequenas transações. Ainda é gratuito, fácil de criar conta, recebe de PJ para PF, tem suporte para várias moedas, é bem seguro e possui ótimo suporte. Remessa Online é o que eu decidi por ora.
OBS: a partir daqui eu já não tenho muita certeza de nada, esta é a síntese do amalgamado de informações que encontrei e está da maneira que eu interpretei. Corrijam-me se houver erros, por favor.
2 - Nesse segundo ponto é que está a merda. Pelo que entendi, nem tudo é maravilha porque o governo além de meter tarifas de conversão da moeda até no teu furico, exige que todo mês seja declarado nos teus impostos os ganhos no exterior pelo famigerado carnê-leão. E é aqui que começou de fato o meu problema.

O problema

Na real mesmo? Eu nunca tive contato na vida com impostos, não tenho emprego (tá difícil aqui onde moro) e nem renda. Não quero dar um de coitadinho da escola pública mas a verdade é que esse tipo de coisa nunca foi nem citado durante meus mais de 10 anos de escola. A questão: Como eu devo proceder?
Pelo que eu entendi, há regras para quem deve declarar o imposto: ser maior de 18, ter renda, ter ganhado x ou investido y ano passado, etc. O Google explica. Entretanto, nos fóruns da vida, é dito que toda renda no exterior deve ser declarada, e fico num impasse. Eu farei, no máximo, e estou sendo generoso, uns 500 USD por mês. Máximo mesmo. Não quero tratar de ilegalidades aqui, tanto que estou perguntando para não sujar meu nome, mas sendo bem franco: as pessoas pagam isso mesmo? Caras, se tu for pessoa física são 27% de impostos que tu tem que pagar pro Governo. Como eu ainda vou estar ganhando acima do câmbio 1:1, ainda estarei lucrando, mesmo que perdendo esse tanto de dinheiro, mas mesmo assim, pra mim é um absurdo ter que dar mais de 1/4 dos meus ganhos pro Governo pra minha rua não ter nem saneamento e usar internet via rádio, lmao. É uma piada, sei que não é bem assim que funciona. Me perdoem a ingenuidade mas foi um choque de realidade.
Para finalizar, já me passaram alternativas, sendo elas:
No final tudo se resume a: preciso realmente pagar esse impostos? Se sim, temos opções legais para burlar (como a dos bancos internacionais) ou só pagar menos?
Bom, era isso. Não postei na megathread de impostos pois percebi que é uma pergunta bem específica e que pode ser aproveitada por outras pessoas também. Desculpem-me o textão, não costumo postar muito nessa minha conta "séria" mas muito obrigado a quem leu, o Reddit é meu salva vidas pra muitas coisas e a internet é o único meio de contato que tenho para esse tipo de informação. Valeu!

Bitcoins são um mimo mais inútil que figurinhas da Copa do Mundo

Em qualquer rodinha de grisalhos hoje em dia, o papo não é mais o Viagra ou Cialis, nem troca de dicas p/ no Tinder atrair gatinhas que queiram homens maduros. É a porra do bitcoin. Essa semana tentei ajudar a vedete do momento a ter um valor real, útil e falhei miseravelmente, o que compartilharei com vossas senhorias nesse rant.
O que tentei nessa semana foi passar a aceitar bitcoins como forma de pagamento aos serviços essensais ao funcionamento da internet: colocation, trânsito IP, CDN e mitigação de DDoS. Isso permitiria que serviços digitais, online, pudessem custear sua operação de infra-estrutura com bitcoins o que por sua vez também permitiria que seus clientes dos joguinhos online, VPN, e-mail etc. pagassem pelo serviço com bitcoin, fazendo uma economia girar.
E me deparei com os seguintes problemas:
Resultado? Não é possível prover um serviço que faça parte de uma cadeia produtiva real, que faça a economia girar e ser remunerado por ele em criptomoedas. Nesse sentido, cédulas do Banco Imobiliário ou figurinhas da Copa do Mundo são mais úteis. Com uma caixa de figurinhas em ano de Copa na porta de uma escola você as troca por dinheiro vivo rápido, sem taxas, no strings attached.
Lembram daqueles jogos estilo Colheita Feliz? Que o povo torrava dinheiro para ter uma árvore de Bis de limão, uma vaca que dava Nescau direto da teta? Hoje o jogo saiu de moda e esses "ativos digitais" valem porcaria nenhuma. Bitcoin é isso, um arquivo da moda que hoje tem muito valor especulativo. Mas quando a moda passar ou você tentar realmente beber o Nescau da sua vaca da Fazendinha Feliz, verá que esse valor não está conectado ao mundo real.
Se não é uma moeda digital, o que é bitcoin então? É na minha humilde avaliação de alguém quem tem uma atividade econômica relevante, que emprega gente, paga impostos e gera riqueza nada mais é do que uma nova modalidade de pirâmide: um esquema abstrato, um produto sem real aplicação no mundo real (ex.: boi gordo, avestruz, TelexFree, TalkFusion) que você tem que pagar para entrar. E quanto mais gente entra, mais o valor do finito bitcoin sobe, os espertos vendem quando o valor fica bem além do que pagaram para entrar e pulam de para-quedas do esquema enquanto os trouxas ficam no avião sem saber que não há mais piloto e a rota é de colisão para o chão.
Bitcoin poderia ser muita coisa boa. O potencial realmente é fantástico, não adianta vir nos comentários tentar me catequizar no que ele poderia/poderá ser. Estou falando do presente. Não vivemos no mundo imaginário The Sims - onde o que imaginamos acontece. Vivemos no mundo real. Onde há câmbio, há fisco, há o estado e seus monopólios. O bitcoin não nos libertará assim como os Simoleons não nos libertaram.
Nada de útil se vende em bitcoin, nada de útil compra em bitcoin, serviços relevantes, bens relevantes não são e não serão trocados usando bitcoin como intermédio. Empresas que mineram, guardam, negociam e convertem bitcoin são tão malévolas quanto bancos tradicionais e seus juros. The cake is a lie.

[How to/Discussion] Bitcoin, Cryptocurrency, coins.ph, and legal implications in the PH

Three quick things you might want to know right away:
I'm not an expert, but I'll share what I know or have observed:
(1) Too late na ba mag-invest sa bitcoin?
When bitcoin hit $100, $1000, and $10000, people were also asking that same question. So the answer is: No one knows. For all we know, pwedeng biglang mag-crash nalang bukas ang bitcoin at di na makabawi. Pwede din tumuloy-tuloy siya hanggang $100,000. Your guess is as good as mine.
(2) How does bitcoin work?
I don't know the nitty gritty, but this was a helpful analogy for a high-level understanding of the concept.
A lot of people say that if you don't understand it, don't invest in it. On the other hand, if the price goes up and I get out before the price goes down, then I made a profit, so I don't have to understand it. Ako, personally, I consider dabbling in cryptocurrencies as an experiment. Gusto ko masabayan kung saan papunta yung technology and I also want to make a profit in the process.
(3) Is bitcoin legal? Me tax ba to?
IANAL, but AFAIK bitcoin is not illegal. Sa alam ko, walang tax to. You can look at bitcoin two ways:
Alam ko in both cases hindi mo kailangan mag-bayad ng tax. If someone knows more about this, please share.
*edit: Apparently, Mutual Funds are taxed but value is reflected to NAVPS. There is also taxes in redemption which I think is 12% VAT in redemption fee between you and the MF company.
Also, someone else mentioned the question of whether or not bitcoin profits should be considered as capital gains*
(4) DON'T INVEST WHAT YOU CAN'T AFFORD TO LOSE
I cannot stress that enough. Wag kayong mag-all in sa bitcoin. Wag niyong i-sacrifice yung mga essential niyo na gastusin sa araw araw, yung mga utang na kailangan niyong bayaran, buoin niyo muna yung emergency funds ninyo, at mag-invest muna kayo sa mas stable na investment (i.e. - MF, UITF) bago niyo paglaruan ang bitcoin.
Bitcoin and cryptocurrency as an investment is very volatile. On any given day, you can gain twice or lose half of your money. At dahil bago palang at di subok yung technology, pwedeng may mga vulnerabilities pa eto na pwede i-exploit ng hackers/scammers.
Wag niyong isugal kung di niyo kayang mawala. Parang pag-ibig lang.
(5) How do I get started with bitcoin in the PH?
The two entry points I hear the most often are: coins.ph and Abra. I've only tried coins.ph. This is what you can do:
Do note that a lot of people consider the rates of coins.ph to be too high and there are better options. Please do your research if this matters significantly to you.
(6) Ano yung mining?
Not into mining. Ang alam ko lang ay may kinalaman to sa kung paano nakadesign ang cryptocurrency, at hindi lang bitcoin ang pwede i-mine. Basically, kailangan mo ng computer na sobrang lakas para gumawa ng madaming computations, para makakuha ng coins. Pero maliit at mabagal lang yung ROI mo dito kung sakali. Tipong madaming buwan bago mo mabawi yung ginastos mo para sa mining rig + sangkatutak na kuryente na kailangan nito. Di ko na pinatulan tong mining.
NOTE: Just to show how unstable this whole cryptocurrency thing is, just today, a popular mining marketplace called NiceHash went down, and along with it, over $60M dollars worth of coins. Some say it got hacked, some say tinangay nung site owner yung pera.
(7) Paano mag-trade?
Pag sinabing trading, eto yung buying and selling of different cryptocurrencies. Para magawa mo to, kailangan mong mag-sign up sa isang exchange at ilipat yung coins mo dun. Halimbawa ng mga cryptocurrency trading exchanges: bittrex, bitfinex, coinbase, poloniex, etc. Otherwise, ang concept niya ay parang trading lang idn sa stock market.
NOTE: Wag ka magtrade kung di mo alam ang ginagawa mo at di mo kayang isugal yung pera mo on top of yung sugal ng pagi-invest sa bitcoin. Madaming nasusunugan ng pera sa trading. Pinaglaruan ko to sandali at malaki pa ang lugi ko na di ko pa nababawi. I should have around +35% of the money I have now if I didn't trade. So try trading at your own risk. It can make or break your cryptocurrency experience.
(8) As much as possible, use a hardware wallet
Just so you know, this is supposedly the most efficient way to secure your coins. Personally, I haven't gotten a hardware wallet yet. I use Bread wallet, which is an open-source software wallet. Sabi naman ng madami secure daw ang Bread. I keep all of my bitcoin in Bread, except for the bitcoin I play around with for trading. If you have 1 or more full bitcoin, you might want to get a hardware wallet though.
(9) Cashing Out
If we still use coins.ph as an example, they have multiple cash out options (cebuana lhullier, mlhullier, security bank, etc). So you can convert your bitcoin back to php and when it's in your php wallet, you can cash it out.
Note though:
Also, someone mentioned buybitcoin.ph as a cash out option
Ano pa ba? Ask and share your cryptocurrency questions, stories, tips, and tricks.

O que são moedas estáveis? USDT, TUSD, GUSD, USDC e USDQ (tradução do texto original - link no rodapé)

O que são moedas estáveis? USDT, TUSD, GUSD, USDC e USDQ
Neste artigo, Slava Mikhalkin fala sobre o USDQ, um stablecoin totalmente algorítmico que oferece confiabilidade e fácil colateralização para o Bitcoin. Trabalhando como um arquiteto Blockchain na PLATINUM ENGINEERING, a Slava colabora com a equipe de + 200 funcionários para desenvolver soluções inovadoras em carteiras de marca branca, plataformas de captação de recursos STOs e IEOs e modelos de negócios de ciclo completo para projetos de criptografia. Uma importante proposta de valor, trazida pela PLATINUM ENGINEERING, é uma abordagem holística, em que um conjunto de talentos versátil ajuda as startups a desenvolver capacidades em TI, marketing e jurídico. Um exclusivo stablecoin USDQ descentralizado apresenta vários algoritmos de estabilização de preços, um intrincado sistema de incentivos para traders e um módulo de análise preditiva orientado por IA. Este romance stablecoin vale a pena notar enquanto ainda está reunindo vapor. Prefácio
É claro que as criptomoedas estão gradualmente fazendo incursões na economia global, aproximando-se da adoção em massa. As criptocorrências oferecem uma série de vantagens - descentralização e confiança, baixas comissões e desintermediação - que facilitam a realização das transações diárias dos usuários. Qualquer pessoa pode transferir valor para todo o mundo, ganhando com o tempo de processamento rápido.
Em comparação, o envio de valores através das fronteiras por meio de sistemas financeiros legados requer longos períodos de espera e taxas, ao mesmo tempo em que torna os usuários presos em processos altamente complexos. Por exemplo, se uma pessoa do Japão quiser enviar algum dinheiro para a Inglaterra, as taxas podem variar de 5% a 10%, dependendo do sistema usado. Além disso, haverá algumas taxas de conversão de moeda. Parece que os jogadores centralizados, que atualmente desfrutam da falta de competição, estabelecem taxas e comissões exatamente como desejam.
E são os comerciantes que realizam transações transfronteiriças que acham que trabalhar com instituições financeiras legadas é mais problemático. Eles continuam perdendo grandes pedaços de seus lucros potenciais, apenas pagando taxas aos processadores de pagamento. Isso faz com que as empresas aumentem seus preços, passando essas despesas para os consumidores comuns. A Crypto oferece uma mudança de paradigma, trazendo para a mesa velocidades relâmpago e taxas mais baixas. Embora as criptomoedas tenham conquistado cada vez mais a atenção dos comerciantes em todo o mundo, ainda há vários obstáculos para uma adoção mais ampla, entre os quais estão a volatilidade dos preços, as limitações de escalabilidade e outras.
A volatilidade é reconhecidamente o maior obstáculo que impede que as empresas usem mais moedas criptografadas. Bitcoin pode experimentar grandes flutuações em apenas algumas horas ou mesmo minutos. Além disso, as principais moedas, como Bitcoin e Ethereum, apresentam problemas de escalabilidade, o que resulta em alto tempo de processamento. Um comerciante, que tem que lidar com centenas de pagamentos diariamente, não seria capaz de conduzir seus negócios eficientemente se as transações ficarem paradas por dias a fio. Além disso, é extremamente difícil para os adeptos converter moedas criptografadas em fiat através dos bancos e outros agentes financeiros com os quais normalmente trabalham.
As criptocorrências procuram oferecer soluções para todos esses problemas.
O que é stablecoin?
Uma stablecoin é uma criptomoeda, cuja arquitetura permite que seu preço seja sempre igual ao preço de outro ativo. A maioria dos stablecoins está vinculada ao dólar americano. Os maiores nomes em criptomoedas são Tether, Gemini Dollar, USDQ, TUSD e outros.
Como os stablecoins conseguem ser tão estáveis?
Ao contrário de outras moedas que flutuam livremente, as criptomoedas estáveis ​​exigem que cada unidade receba uma unidade da moeda fiduciária. Por exemplo, Tether (USDT) fixa 1 USDT a 1 USD na base de um para um. Desta forma, stablecoins estão em algum lugar entre cryptocurrencies e regular fiats. O Tether é baseado em seu próprio blockchain que é construído sobre os sistemas Bitcoin, Litecoin e Ethereum.
Embora o Tether seja o maior stablecoin, há uma série de preocupações quanto às suas operações. A maior delas é a contínua controvérsia quanto às reservas fiduciárias, que o emissor deve armazenar na relação um-para-um com o número de unidades Tether emitidas. A empresa tem dito que a auditoria será feita em um futuro próximo, mas há apenas algumas semanas começou a afirmar que não é apenas o dinheiro, mas também empréstimos para outras empresas que podem ser registradas como reservas fiduciárias. Essas declarações resultaram em crescente desconfiança entre os entusiastas da criptografia.
Outro projeto é o TrueUSD (TUSD). Ele também atrela ao USD. A diferença com o Tether é a abertura para auditorias e transparência. A empresa está aberta a auditorias de terceiros, publica os relatórios devidamente verificados sobre as reservas fiduciárias que detém. Além disso, os usuários desfrutam de proteções legais.
O USDC é outro stablecoin que foi criado pelo famoso Círculo de troca de criptomoedas. Assim como TUSD, se oferece conformidade regulatória e transparência. O grande problema em todos esses sistemas é o fato de que eles permitem que as autoridades aproveitem os fundos dos usuários, o que nega completamente a própria idéia de descentralização e anti-censura, na qual a criptografia é construída.
O USDQ é diferente de outros stablecoins, uma vez que não é respaldado pela moeda fiduciária, mas pelo Bitcoin e outras dez criptomoedas no futuro. Isso permite que o ecossistema evite lidar com sistemas financeiros legados. Através do processo de supercollateralização, USDQ transforma criptomoedas altamente voláteis no USDQ indexado ao USD, que é perfeito para armazenar valor e processar transações na economia externa, sem qualquer risco de mudanças de preço. A moeda está sendo desenvolvida pela PLATINUM ENGINEERING com a pequena comunidade crescendo lentamente em torno do projeto.
Por que precisamos de stablecoins?
Stablecoins avançaram como uma nova iteração em criptomoedas, permitindo tratar de questões como alta volatilidade e interações com sistemas financeiros legados.
Moedas como o USDQ garantem que vários mecanismos sejam usados ​​para estabilizar os preços na pegada do USD. Os traders podem facilmente mudar seus Bitcoins para USDQ e, assim, evitar o impacto negativo em mudanças indesejadas de preços. Stablecoins são muito fáceis de usar, o que é um benefício para os usuários não-techy. Qualquer pessoa de todo o mundo pode rapidamente converter fiat em stablecoins, sem qualquer necessidade de pensar em futuras mudanças de preço e sem se preocupar com riscos potenciais de perder seus fundos. Como regra geral, você sempre encontrará vários pilares em trocas de criptografia, permitindo que os comerciantes se movimentem rapidamente em estábulos e outros criptos.
Como já falamos acima, os pagamentos transfronteiriços ganham mais com o uso dos stablecoins. Esta espécie híbrida entre decreto e criptografia ajudará a abrir o valor oculto no comércio global, totalizando trilhões de dólares em lucros para as partes interessadas.
O USDQ é stablecoin descentralizado, que usa algoritmos para oferecer maior estabilidade e confiabilidade. Totalmente on-chain e monitorado por robôs AI de alta velocidade, o ecossistema oferece defesas confiáveis ​​contra ataques e ações maliciosas. Primeiro executado na linha de adaptadores, o USDQ é trazido pela PLATINUM ENGINEERING Team, buscando soluções inovadoras em colateralização, usando mecanismos de estabilização e oráculos para estabilizadores de alta resistência. Totalmente anónimo, o USDQ ultrapassa os limites deste mundo legado.
PLATINUM ENGINEERING compartilha abertamente sobre o seu desenvolvimento e vetores para o crescimento, permitindo que as partes interessadas aprendam sobre soluções de ponta no domínio blockchains / crypto. A PLATINUM ENGINEERING já ajudou mais de 150 projetos de criptografia a crescer através da emergente economia blockchain do futuro. As empresas ficariam maravilhadas com as novas capacidades que poderiam obter através da tokenização de seus modelos de negócios, automatizando os processos de negócios de rotina e atraindo investidores para os mercados de criptografia. A equipe dá as boas-vindas à comunidade para entrar em contato diretamente através dos grupos oficiais do Telegram, Facebook ou LinkedIn. Os leitores aprenderão como obter novas vantagens competitivas tocando no blockchain em seu blog.

É claro que as criptomoedas estão gradualmente fazendo incursões na economia global, aproximando-se da adoção em massa. As criptocorrências oferecem uma série de vantagens - descentralização e confiança, baixas comissões e desintermediação - que facilitam a realização das transações diárias dos usuários. Qualquer pessoa pode transferir valor para todo o mundo, ganhando com o tempo de processamento rápido.

Em comparação, o envio de valores através das fronteiras por meio de sistemas financeiros legados requer longos períodos de espera e taxas, ao mesmo tempo em que torna os usuários presos em processos altamente complexos. Por exemplo, se uma pessoa do Japão quiser enviar algum dinheiro para a Inglaterra, as taxas podem variar de 5% a 10%, dependendo do sistema usado. Além disso, haverá algumas taxas de conversão de moeda. Parece que os jogadores centralizados, que atualmente desfrutam da falta de competição, estabelecem taxas e comissões exatamente como desejam.

E são os comerciantes que realizam transações transfronteiriças que acham que trabalhar com instituições financeiras legadas é mais problemático. Eles continuam perdendo grandes pedaços de seus lucros potenciais, apenas pagando taxas aos processadores de pagamento. Isso faz com que as empresas aumentem seus preços, passando essas despesas para os consumidores comuns. A Crypto oferece uma mudança de paradigma, trazendo para a mesa velocidades relâmpago e taxas mais baixas. Embora as criptomoedas tenham conquistado cada vez mais a atenção dos comerciantes em todo o mundo, ainda há vários obstáculos para uma adoção mais ampla, entre os quais estão a volatilidade dos preços, as limitações de escalabilidade e outras.

A volatilidade é reconhecidamente o maior obstáculo que impede que as empresas usem mais moedas criptografadas. Bitcoin pode experimentar grandes flutuações em apenas algumas horas ou mesmo minutos. Além disso, as principais moedas, como Bitcoin e Ethereum, apresentam problemas de escalabilidade, o que resulta em alto tempo de processamento. Um comerciante, que tem que lidar com centenas de pagamentos diariamente, não seria capaz de conduzir seus negócios eficientemente se as transações ficarem paradas por dias a fio. Além disso, é extremamente difícil para os adeptos converter moedas criptografadas em fiat através dos bancos e outros agentes financeiros com os quais normalmente trabalham.

As criptocorrências procuram oferecer soluções para todos esses problemas.

O que é stablecoin?

Uma stablecoin é uma criptomoeda, cuja arquitetura permite que seu preço seja sempre igual ao preço de outro ativo. A maioria dos stablecoins está vinculada ao dólar americano. Os maiores nomes em criptomoedas são Tether, Gemini Dollar, USDQ, TUSD e outros.

Como os stablecoins conseguem ser tão estáveis?

Ao contrário de outras moedas que flutuam livremente, as criptomoedas estáveis ​​exigem que cada unidade receba uma unidade da moeda fiduciária. Por exemplo, Tether (USDT) fixa 1 USDT a 1 USD na base de um para um. Desta forma, stablecoins estão em algum lugar entre cryptocurrencies e regular fiats. O Tether é baseado em seu próprio blockchain que é construído sobre os sistemas Bitcoin, Litecoin e Ethereum.

Embora o Tether seja o maior stablecoin, há uma série de preocupações quanto às suas operações. A maior delas é a contínua controvérsia quanto às reservas fiduciárias, que o emissor deve armazenar na relação um-para-um com o número de unidades Tether emitidas. A empresa tem dito que a auditoria será feita em um futuro próximo, mas há apenas algumas semanas começou a afirmar que não é apenas o dinheiro, mas também empréstimos para outras empresas que podem ser registradas como reservas fiduciárias. Essas declarações resultaram em crescente desconfiança entre os entusiastas da criptografia.

Outro projeto é o TrueUSD (TUSD). Ele também atrela ao USD. A diferença com o Tether é a abertura para auditorias e transparência. A empresa está aberta a auditorias de terceiros, publica os relatórios devidamente verificados sobre as reservas fiduciárias que detém. Além disso, os usuários desfrutam de proteções legais.

O USDC é outro stablecoin que foi criado pelo famoso Círculo de troca de criptomoedas. Assim como TUSD, se oferece conformidade regulatória e transparência. O grande problema em todos esses sistemas é o fato de que eles permitem que as autoridades aproveitem os fundos dos usuários, o que nega completamente a própria ideia de descentralização.

A plataforma da QDAO, uma das melhores plataformas do mundo está com um Airdrop, extraordinário para quem está atras de recompensas por pequenas tarefas e recompensas grandes.
Venha fazer parte dessa família.

Decred Journal – September 2018

Note: you can read this on GitHub (link), Medium (link) or old Reddit (link).

Development

Final version 1.3.0 of the core software was released bringing all the enhancements reported last month to the rest of the community. The groundwork for SPV (simplified payment verification) is complete, another reduction of fees is being deployed, and performance stepped up once again with a 50% reduction in startup time, 20% increased sync speed and more than 3x faster peer delivery of block headers (a key update for SPV). Decrediton's integrations of SPV and Politeia are open for testing by experienced users. Read the full release notes and get the downloads on GitHub. As always, don't forget to verify signatures.
dcrd: completed several steps towards multipeer downloads, improved introduction to the software in the main README, continued porting cleanups and refactoring from upstream btcd.
Currently in review are initial release of smart fee estimator and a change to UTXO set semantics. The latter is a large and important change that provides simpler handling, and resolves various issues with the previous approach. A lot of testing and careful review is needed so help is welcome.
Educational series for new Decred developers by @matheusd added two episodes: 02 Simnet Setup shows how to automate simnet management with tmux and 03 Miner Reward Invalidation explains block validity rules.
Finally, a pull request template with a list of checks was added to help guide the contributors to dcrd.
dcrwallet: bugfixes and RPC improvements to support desktop and mobile wallets.
Developers are welcome to comment on this idea to derive stakepool keys from the HD wallet seed. This would eliminate the need to backup and restore redeem scripts, thus greatly improving wallet UX. (missed in July issue)
Decrediton: bugfixes, refactoring to make the sync process more robust, new loading animations, design polishing.
Politeia: multiple improvements to the CLI client (security conscious users with more funds at risk might prefer CLI) and security hardening. A feature to deprecate or timeout proposals was identified as necessary for initial release and the work started. A privacy enhancement to not leak metadata of ticket holders was merged.
Android: update from @collins: "Second test release for dcrandroid is out. Major bugs have been fixed since last test. Latest code from SPV sync has been integrated. Once again, bug reports are welcome and issues can be opened on GitHub". Ask in #dev room for the APK to join testing.
A new security page was added that allows one to validate addresses and to sign/verify messages, similar to Decrediton's Security Center. Work on translations is beginning.
Overall the app is quite stable and accepting more testers. Next milestone is getting the test app on the app store.
iOS: the app started accepting testers last week. @macsleven: "the test version of Decred Wallet for iOS is available, we have a link for installing the app but the builds currently require your UDID. Contact either @macsleven or @raedah with your UDID if you would like to help test.".
Nearest goal is to make the app crash free.
Both mobile apps received new design themes.
dcrdata: v3.0 was released for mainnet! Highlights: charts, "merged debits" view, agendas page, Insight API support, side chain tracking, Go 1.11 support with module builds, numerous backend improvements. Full release notes here. This release featured 9 contributors and development lead @chappjc noted: "This collaboration with @raedahgroup on our own block explorer and web API for @decredproject has been super productive.".
Up next is supporting dynamic page widths site wide and deploying new visual blocks home page.
Trezor: proof of concept implementation for Trezor Model T firmware is in the works (previous work was for Model One).
Ticket splitting: updated to use Go modules and added simnet support, several fixes.
docs: beginner's guide overhaul, multiple fixes and cleanups.
decred.org: added 3rd party wallets, removed inactive PoW pools and removed web wallet.
@Richard-Red is building a curated list of Decred-related GitHub repositories.
Welcome to new people contributing for the first time: @klebe, @s_ben, @victorguedes, and PrimeDominus!
Dev activity stats for September: 219 active PRs, 197 commits, 28.7k added and 18.8k deleted lines spread across 6 repositories. Contributions came from 4-10 developers per repository. (chart)

Network

Hashrate: started and ended the month around 75 PH/s, hitting a low of 60.5 and a new high of 110 PH/s. BeePool is again the leader with their share varying between 23-54%, followed by F2Pool 13-30%, Coinmine 4-6% and Luxor 3-5%. As in previous months, there were multiple spikes of unidentified hashrate.
Staking: 30-day average ticket price is 98 DCR (+2.4). The price varied between 95.7 and 101.9 DCR. Locked DCR amount was 3.86-3.96 million DCR, or 45.7-46.5% of the supply.
Nodes: there are 201 public listening nodes and 325 normal nodes per dcred.eu. Version distribution: 5% are v1.4.0(pre) dev builds (+3%), 30% on v1.3.0 (+25%), 42% on v1.2.0 (-20%), 15% on v1.1.2 (-7%), 6% on v1.1.0. More than 76% of nodes run v1.2.0 and higher and therefore support client filters. Data as of Oct 1.

ASICs

Obelisk posted two updates on their mailing list. 70% of Batch 1 units are shipped, an extensive user guide is available, Obelisk Scanner application was released that allows one to automatically update firmware. First firmware update was released and bumped SC1 hashrate by 10-20%, added new pools and fixed multiple bugs. Next update will focus on DCR1. It is worth a special mention that the firmware source code is now open! Let us hope more manufacturers will follow this example.
A few details about Whatsminer surfaced this month. The manufacturer is MicroBT, also known as Bitwei and commonly misspelled as Bitewei. Pangolinminer is a reseller, and the model name is Whatsminer D1.
Bitmain has finally entered Decred ASIC space with their Antminer DR3. Hash rate is 7.8 TH/s while pulling 1410 W, at the price of $673. These specs mean it has the best GH/W and GH/USD of currently sold miners until the Whatsminer or others come out, although its GH/USD of 11.6 already competes with Whatsminer's 10.5. Discussed on Reddit and bitcointalk, unboxing video here.

Integrations

Meet our 17th voting service provider: decredvoting.com. It is operated by @david, has 2% fee and supports ticket splitting. Reddit thread is here.
For a historical note, the first VSP to support ticket splitting was decredbrasil.com:
@matheusd started tests on testnet several months ago. I contacted him so we could integrate with the pool in June this year. We set up the machine in July and bought the first split ticket on mainnet, using the decredbrasil pool, on July 19. It was voted on July 30. After this first vote on mainnet, we opened the tests to selected users (with more technical background) on the pool. In August we opened the tests to everyone, and would call people who want to join to the #ticket_splitting channel, or to our own Slack (in Portuguese, so mostly Brazilian users). We have 28 split tickets already voted, and 16 are live. So little more than 40 split tickets total were bought on decredbrasil pool. (@girino in #pos-voting)
KuCoin exchange listed DCBTC and DCETH pairs. To celebrate their anniversary they had a 99% trading fees discount on DCR pairs for 2 weeks.
Three more wallets integrated Decred in September:
ChangeNow announced Decred addition to their Android app that allows accountless swaps between 150+ assets.
Coinbase launched informational asset pages for top 50 coins by market cap, including Decred. First the pages started showing in the Coinbase app for a small group of testers, and later the web price dashboard went live.

Adoption

The birth of a Brazilian girl was registered on the Decred blockchain using OriginalMy, a blockchain proof of authenticity services provider. Read the full story in Portuguese and in English.

Marketing

Advertising report for September is ready. Next month the graphics for all the ads will be changing.
Marketing might seem quiet right now, but a ton is actually going on behind the scenes to put the right foundation in place for the future. Discovery data are being analyzed to generate a positioning strategy, as well as a messaging hierarchy that can guide how to talk about Decred. This will all be agreed upon via consensus of the community in the work channels, and materials will be distributed.
Next, work is being done to identify the right PR partner to help with media relations, media training, and coordination at events. While all of this is coming up to speed, we believe the website needs a refresher reflecting the soon to be agreed upon messaging, plus a more intuitive architecture to make it easier to navigate. (@Dustorf)

Events

Attended:
Upcoming:
We'll begin shortly reviewing conferences and events planned for the first half of 2019. Highlights are sure to include The North American Bitcoin Conference in Miami (Jan 16-18) and Consensus in NYC (May 14-16). If you have suggestions of events or conferences Decred should attend, please share them in #event_planning. In 2019, we would like to expand our presence in Europe, Asia, and South America, and we're looking for community members to help identify and staff those events. (@Dustorf)

Markets

In September DCR was trading in the range of USD 34-45 / BTC 0.0054-0.0063. On Sep 6, DCR revisited the bottom of USD 34 / BTC 0.0054 when BTC quickly dropped from USD 7,300 to 6,400. On Sep 14, a small price rise coincided with both the start of KuCoin trading and hashrate spike to 104 PH/s. Looking at coinmarketcap charts, the trading volume is a bit lower than in July and August.
As of Oct 4, Decred is #18 by the number of daily transactions with 3,200 tx, and #9 by the USD value of daily issuance with $230k. (source: onchainfx)
Interesting observation by @ImacallyouJawdy: while we sit at 2018 price lows the amount locked in tickets is testing 2018 high.

Stable coins

What are Stable Coins? USDT, TUSD, GUSD, USDC and USDQ

In this article, Slava Mikhalkin talks aboutUSDQ, a fully algorithmic stablecoin that offers reliability and easy collateralization for Bitcoin. Working as a Blockchain Architect with PLATINUM ENGINEERING, Slava collaborates within the +200-employee team to develop bleeding edge solutions in white-label wallets,STOs and IEOs fundraising platforms, and full-cycle business models for crypto projects. A key value proposition, brought by PLATINUM ENGINEERING, is a holistic approach, where a versatile talent pool helps startups build up capabilities in IT, marketing and legal. A unique decentralized stablecoin USDQ features various price stabilization algorithms, an intricate system of incentives for traders and AI-driven predictive analytics module. This novel stablecoin is worth noting while it’s still gathering steam.
Foreword
It's clear that cryptocurrencies are gradually making inroads into the global economy, moving closer to mass adoption. Cryptocurrencies offer a number of advantages - decentralization and trust, lower commissions and disintermediation - that make it easier for users to carry out their daily transactions. Anybody can transfer value around the globe, winning from fast processing time.
In comparison, sending value across borders via legacy financial systems requires lengthy waiting periods and fees, while also making users stuck into highly complex processes. For instance, if a person from Japan wants to send some money to England, the fees can range anywhere from 5% up to 10%, depending on the system being used. In addition, there will be some currency conversion fees. It seems that centralized players, currently enjoying lack of competition, set up fees and commissions just as they wish.
And it's merchants that carry out cross-border transactions that find working with legacy finance institutions most troublesome. They keep losing hefty chunks from their potential profits, just paying out fees to payment processors. This makes businesses hike up their prices, passing these expenses to ordinary consumers. Crypto offers a paradigm shift change, bringing to the table lightning speeds and lower fees. Although cryptocurrencies have been winning more and more attention from merchants worldwide, there's still a number of roadblocks to wider adoption, among which are price volatility, scalability limitations and others.
Volatility is admittedly the biggest hurdle that prevents businesses from using cryptocurrencies more. Bitcoin can experience huge fluctuations in just a matter of hours or even minutes. In addition, major coins like Bitcoin and Ethereum present scalability issues, which results in high processing time. A merchant, who has to handle hundreds of payments on a daily basis, would not be able to conduct their business efficiently if transactions get stuck for days on end. On top of that, it's extremely hard for adopters to convert cryptocurrencies into fiat via the banks and other financial agents they usually work with.
Cryptocurrencies seek to offer solutions to all of these issues.
What is stablecoin?
A stablecoin is a cryptocurrency, whose architecture enables its price to always equal the price of another asset. Most of the stablecoins are pegged to USD. The biggest names in cryptocurrencies are Tether, Gemini Dollar, USDQ, TUSD and others.
How do stablecoins manage to be so stable?
As opposed to other coins that float freely, stable cryptocurrencies require that each unit is backed with a unit of the fiat currency. For instance, Tether (USDT) pegs 1 USDT to 1 USD on the one-to-one basis. In this way, stablecoins are somewhere between cryptocurrencies and regular fiats. Tether is based on its own blockchain that is built on top of Bitcoin, Litecoin and Ethereum systems.
Although Tether is the biggest stablecoin, there's a number of concerns as to its operations. The biggest one is the continuing controversy as to the fiat reserves, which the issuer is supposed to store on the one-to-one ratio to the number of issued Tether units. The company has been saying that the audit will be done in the near future, but just several weeks ago it started to claim that it's not only the cash, but also loans to other companies that can be recorded as fiat reserves. These statements resulted in growing distrust among crypto enthusiasts.
Another project is TrueUSD (TUSD). It also pegs to USD. The difference with Tether is the openness to audits and transparency. The company is open to third-party audits, it publishes the duly verified reports on the fiat reserves it holds. In addition, users enjoy legal protections.
USDC is another stablecoin that was created by the famous cryptocurrency exchange Circle. Just as TUSD, if offers regulatory compliance and transparency. The big problem about all these systems is the fact that they enable authorities to seize users’ funds, which completely negates the very idea of decentralization and anti-censorship, on which crypto is built.
USDQ is different from other stablecoins as it's not backed by the fiat currency, but by Bitcoin and other top-10 cryptocurrencies in the future. This enables the ecosystem to avoid dealing with legacy financial systems. Through the overcollateralization process, USDQ turns highly volatile cryptocurrencies into the USD-pegged USDQ that is perfect for storing value and processing transactions in the external economy without any risk of price changes. The coin is being developed by PLATINUM ENGINEERING with the small community slowly growing around the project.
Why do we need stablecoins?
Stablecoins have advanced as a new iteration on cryptocurrencies, enabling to address such issues as high volatility and interactions with legacy financial systems.
Coins like USDQ make sure that various mechanisms are used in order to stabilize the prices at the USD peg. Traders can easily change their Bitcoins into USDQ and thus prevent the negative impact on unwanted prices changes. Stablecoins are very easy to use, which is a boon for non-techy adopters. Any person from around the world can quickly convert fiats into stablecoins, without any need to think about future price changes and without worrying about potential risks for losing their funds. As a rule, you'll always find various stablecoins on crypto exchanges, enabling traders to quickly move around stables and other cryptos.
As we've spoken above, cross-border payments win most from using the stablecoins. This hybrid species between fiat and crypto will help open up the hidden value in global trade, amounting to trillions of dollars in profits for stakeholders.
USDQ is decentralized stablecoin, which uses algorithms to offer higher stability and reliability. Fully on-chain and monitored by high-speed AI robots, ecosystem offers reliable defences against malicious acts and attacks. First run in line of fiat-pegs, USDQ is brought byPLATINUM ENGINEERING Team, looking to edge together innovative solutions in collateralization, using stabilizing mechanisms and oracles for high-endurance stablecoins. Fully anonymous, USDQ breaks limits out of this legacy world.
PLATINUM ENGINEERING openly shares about its development and vectors for growth, enabling stakeholders to learn about cutting-edge solutions in the blockchains/crypto domain. PLATINUM ENGINEERING has already helped over 150 crypto projects to grow through emerging blockchain economy of the future. Businesses would be amazed at new capabilities they can obtain through tokenizing their business models, automating routine business processes and drawing investors on crypto markets. The team welcomes the community to contact directly via the official groups in Telegram, Facebook or LinkedIn. Readers will learn how to obtain new competitive advantages by tapping into blockchain in their blog.

Features WAVES DEX and its integration into the marketplace NYiGDE?.

Features WAVES DEX and its integration into the marketplace NYiGDE?.
https://preview.redd.it/sniul3l1vue11.jpg?width=999&format=pjpg&auto=webp&s=9201a409c98dfe8fa48e0f2e58ca3a3759212901
Waves is a transparent, completely open, decentralized crypto-exchange, successfully operating on Blockchain technology. The platform allows any company, a new start-up to create a token in just a few minutes, and more than 10 thousand crypto-enthusiasts have already used it.
On the Waves exchange, many positive facts are written, but is it so good, as the world's online resources say …
Our team for three years developed a multi-lingual platform for global e-commerce, while enjoying many years of experience in the field of IT. Waves is one of the most secure Blockchain platforms that have a high level of user protection. For this reason, we chose to create our NYIGDE token for the WAVES DEX platform. Thus, we are able to provide users of the platform and token holders with reliability, security, data confidentiality and ease of use.
Security on Waves. Users' funds are stored not on the stock exchange itself, but in a personal purse that can be controlled solely by the user. How to create your wallet and buy NYIGDE token click here.
You can make transactions absolutely safely, without any risks of losing assets in hacker attacks. Thus, your token are not connected with the exchange, and in any situation controlled by you, and only.
The Waves application was audited in Kudelski Security. The purpose of the check was to detect even the slightest flaws in the security system. The audit was very successful, there were no critical problems. This led us to a single conclusion: the exchange demonstrates a high level of safety engineering, has a fairly good choice of cryptographic components, has a clear design and code. You can find a detailed audit report here.
Another positive action was the addition of Waves NG Protocol, Smart Contracts and Mobile Dex, which gave the crypto-exchange additional advantages and significantly improved the work.
And now more specifically about the advantages of WAVES DEX and its integration into the platform NYIGDE?:
\* Successful implementation of the Waves NG protocol, which increases the speed of transactions on the network: hundreds of transactions per second, ~ 6000 per minute. This ensures long-term scalability and performance of our platform.
\* We are implementing intellectual contracts in the functional platform NYIGDE?, which are available in an open form on WAVES.
\* Waves uses the "Proof of stake" consensus algorithm, which is times better than "Proof of work", which is used by other equally well-known crypto-exchanges.
\ Waves allows you to commit more than 100 transactions per second, while *Bitcoin gives only 3, and Ethereum - 5.
\* The open mobile WAVES DEX enables users of our platform to easily and safely operate tokens from a personal mobile device.
\* Quick scaling Waves, and accordingly, NYiGDE?.
\* Low transaction costs.
\* A successful security audit.
\* Lock for improved security.
\* Simple interface, convenient and affordable functionality.
\* Easy to manage, no need to download the blockchain.
\* Available smart contracts, through which it is possible to effectively control the flow of personal funds, without involving third parties.
\* Absolute decentralization, peer-to-peer trade within the WAVES Client application.
\* Trading any pair of Waves, combining with close to real time.
\* Transfer of funds in the form of Fiats, fully compatible and licensed gateways for the blockchain, Bitcoin, Ethereum and other currencies + EUR, USD to verified users.
\* Tokens are easily convertible to other crypto- and fiat assets.
The above-mentioned advantages of crypto-exchange Waves, we hope, more than enough. Many have told, explained and argued, and now, friends, it's up to you. Find out more about the NYIGDE token on the Landing page, follow the news in the Token Sale Event NYiGDE section

Another way to look at the bubbles

This is a follow up to a post I made a couple of days ago looking at the log-linear regression of bitcoin prices:
http://www.reddit.com/BitcoinMarkets/comments/21smpsome_perspective_on_the_current_pessimism/
This post is going to look at this regression again, but this time using it to make comparisons between Bitcoin's bubbles.
One way to compare Bitcoin's bubble periods is by categorizing periods on the basis of how far away they are from the regression line. The set of these distance measures is known as the 'residuals'. What I've done in this chart is colour code each price depending on where on a set of ranges its residual value falls.
http://i.imgur.com/y1Klgum.png
How did I select the ranges I did? Semi-arbitrarily (if anyone knows of a less-arbitrary way to do this let me know). The residuals seem to cluster to some degree around certain ranges when you look at them in a histogram. So that's why I chose the ranges that I did.
http://i.imgur.com/FbqtIfV.png
What I think a chart like this is representing is how far away bitcoin is from its exponential growth trend. So a bubble is interpreted relative to that growth trend and not its absolute growth in value. This gives different results from when you just look at absolute price growth.
For example - if you compare the 2012/13 bubble with the 2013/14 bubble on the basis of the absolute amount of price growth then the former of these is the larger bubble with about 13x price growth compared to about 8x. But from the perspective of the price relative to the exponential growth trend, the latter is clearly larger. How is this possible, you can see it easily from the chart. The 2012/13 bubble came off a much larger slump relative to the trend (a blue zone) - whereas the 2013/14 bubble had less ground to make up. It started in a green zone. Furthermore, while the 2012/13 bubble makes it into the orange zone - it only stays there briefly. It's really mostly a yellow level event. The 2013/14 bubble is is definitively an orange level event and even gets into the red zone for a day.
The 2011 bubble is less interesting from this perspective since it is big in all respects - both price growth and its residuals. Notice also how some quite large price increases (3x in jun-aug 2012) don't even count as bubbles on this analysis even though they have the same triangle shape as the others.
In terms of the current downtrend it provides an extra rationalisation as to why things aren't that grim. We are currently in a green period - which is the most common colour by far. Green is not a bad place to be if you care about whether or not Bitcoin is maintaining its long term trend. Blue is where things start to get concerning. If that chart ever registers a significant period of purple - that's when I'm going to start to freak out for bitcoin's long term future.
As always - take this stuff with large pinches of salt. If you look at this stuff yourself, I recommend trying to come up with alternative (principled) ways of choosing your colour regions. You can also experiment with using different time frames. If you start your regression at the beginning of the 2012/13 bubble then it becomes much larger than the 2013/14 bubble. I personally don't think this is appropriate if you are looking at the long term exponential growth - but you gotta bear it in mind.
One other thing - this data swaps from the mtgox to bitstamp data. I feel mtgox data is generally to be avoided, because of the way it skewed the market - but it's all we have from the early periods.

Estimating DPR's income after expenses & exchange rate

The FBI indictment states that SDPR earned ฿614,305 in commissions. It's been suggested that the expense of running SR, and the large changes in the exchange rate, may substantially reduce how many bitcoins DPR actually could have saved up, possibly to as low as ฿"150-200k". (The logic here is that if SR earns commissions of ฿100 in 2011 but needs to pay $100 of hosting bills, it needs to sell all ฿100 but in 2013, it would need to sell only ฿1.)
DPR surely spent some of the commissions on running SR & himself, but running a website isn't that expensive, and how badly the exchange rate bites will depend on details like how it fluctuated over time, how sales grew over time, and how big the expenses really are. The reduction could be tiny, or it could be huge. It's hard to tell based just on a gut estimate.
So: below, I take estimates of SR growth from Christin 2013's crawl and the FBI indictment, infer linear growth of SR sales, estimate daily expenses, and combine it with historical Bitcoin exchange rates to show that DPR probably has most of his bitcoins and 200k or lower is right out.

Model

My strategy is to model Silk Road's growth as linear in dollar amounts, but with different amounts of bitcoins each day depending on the exchange rate, subtract a daily operating cost, and then sum the commissions.
So say that on 1 January 2012, SR did $10k of business, and the exchange rate was 1:100, so ฿100 in turnover, and SR gets an average commission of 7.4%, so it would get ฿7.4.
To do this, I need to estimate the revenue each day, the expenses each day, the commission each day, and the exchange rate each day. Then I can multiply revenue by commission, subtract the expense, and sum the left overs to get an estimate of the total bitcoins available to DPR which he could (or could not) have spent.

Expenses

  1. Employees: we know that Libertas and one or two others were employed at salaries of $1-2k per week. I'll assume there were 2 others, and each was paid the max of $2k per week, which means total daily employee expenses is (2 * 2000) / 7 = $571 per day. (Unfortunately, the indictment doesn't give any clear indication of their numbers, just referring to them as 'they'.)
    This is a conservative estimate since I'm pretty sure that SR was a one-man operation until probably in 2012.
  2. The servers: we know there were at least 2 servers (the main site, and the forums). The task of hosting the sites does not seem to be too bandwidth or disk-space intensive, and servers are extremely cheap these days. The use of DataClub.biz and GigaTux suggest DPR was using cheap VPSes. I'll estimate a monthly expense of $500 ($250 a piece) which per day is $16.
    This is also very conservative.
  3. DPR: his rent of $1000/month has been widely bruited about, and in general he reportedly spent little. Makes sense to me, I've met and seen the rooms of a few well-paid geeks in SF like DPR, and I would believe them if they said they didn't spend much money on anything but rent & food. I'll bump this up by $1000 for food and all expenses, since he apparently didn't even eat out very much. So $2000/31=$65.
    Doubling his rent for total expenses is probably also conservative; for most people, rent is not >50% of income, but SF is incredibly expensive to live in.
This gives a daily expense of $652 (or a monthly total of $19.1k in expenses). As you can see, the employees are by far the most expensive part of running SR in my estimate, which makes me wonder if maybe Libertas was the only employee.

Hitmen

Assuming the details about DPR hiring hitmen in the indictments are reasonably accurate, we can throw in two large expenses:
  1. an $80k expenditure for killing his Maryland employee. The first payment of $40k was made on 4 February 2013 and the second/final payment of $40k was made on 1 March 2013 (pg9). If we use the exchange rate of those two days, then the hit cost DPR (40000 / 20.42) + (40000 / 34.24) = ฿3127
  2. the second hit was priced in bitcoins (pg23):
    Through further messages exchanged on March 31, 2013, DPR and redandwhite agreed upon a price of 1,670 Bitcoins
So the hits cost DPR somewhere around ฿4797. An extremely large and painful amount, by most standards, but still nowhere near ฿10k - much less higher.

Revenue over time: first and last days

Christin:
Table 3 provides a breakdown of the feedback ratings from 184,804 feedback instances we collected...In Figure 12, we plot an estimate of the daily commissions collected by Silk Road operators as a function of time. We simply reuse the previous estimates, and apply both the fixed 6.23% rate, and the schedule of Table 4 to each item. We find that the new schedule turns out to yield on average a commission corresponding to approximately 7.4% of the item price.
The FBI:
From February 6, 2011 to July 23, 2013 there were approximately 1,229,465 transactions completed on the site...$79.8 million (USD) in commissions.
According to Bitcoin Charts, on 23 July 2013, the MtGox price was $91. (As the most famous exchange, any FBI estimate almost certainly used it.) So that implies $79,800,000/91=฿876,923. Or to put it the other way, at $79.8m in transactions, then using Christin's 7.4% estimate, total sales were $1,078,000,000 or ฿10,780,000.
Wikipedia says "These transactions involved 146,946 unique buyer accounts, and 3,877 unique vendor accounts.", and "The total revenue generated from transactions was 9,519,664 bitcoins. Commissions collected from the sales by Silk Road amounted to 614,305 bitcoins."
(So the numbers aren't too different: 614k vs 876k and 10.8m vs 9.5m.)
We'll set 6 February 2011 to $10 in sales (probably not too far from the truth). But what about 23 July 2013? pg20 of the indictment says:
For example, on July 21, 2013 alone, DPR received approximately 3,237 separate transfers of Bitcoins into his account, totaling approximately $19,459. Virtually all of these transactions are labeled "commission".
19459 / 0.074 = $262,959 that day. $20k in commissions is extremely impressive, since Christin estimates only $4k/day commissions as late as the end of July 2012 - so SR must have grown by 500% from 2012 to 2013. We use this revenue estimate as our endpoint and interpolate from $10 to $262,959 over the ~900 days SR existed. This is a conservative way of modeling SR, since the graphs in Christin indicate that SR saw sigmoid growth in 2012, and 2013 would've seen even more growth (to be consistent with the 2013 July commission datapoint being 5x the 2012 July commission datapoint).

Exchange rate

I grab weighted price for each day between 6 February 2011 & 23 July 2013, and stuff it in a CSV.

Analysis

R> sr <- read.csv("http://dl.dropboxusercontent.com182368464/dpr-exchangerate.csv") R> sr$Sales <- c(10, rep(NA, 890), 262959, NA, NA) R> # revenue increased by $300 a day: R> l <- lm(Sales ~ as.numeric(Date), data=sr); l Coefficients: (Intercept) as.numeric(Date) -285 295 R> sr$Sales <- predict(l, newdata=sr) R> sum(with(sr, (Sales * 0.074 - 652) / ExchangeRate)) [1] 803397 
Or we can run the estimate the other way: if DPR had to spend $652 a day and converted at that day's exchange rate, and we took into account the hitmen, how many bitcoins would he have spent in total?
R> sum(with(sr, 652 / ExchangeRate)) [1] 127154 R> (614305 - 127154) - 4797 [1] 482354 

Conclusion

Obviously ฿803k > ฿614k, which implies that the linear model overestimates sales in the early life of SR; but going the other direction and estimating just from costs & hitmen & total commission, we still wind up with nearly ฿500k (and that was after making a bunch of highly conservative assumptions). The fewer sales (and commissions) early on, the less of a fixed number of bitcoins will be sold. So, while it may initially sound plausible that DPR could have been forced to part with say ฿400k to pay for SR and sundry expenses, the distribution of sales and fluctuations of Bitcoin value mean that this simply does not seem to be the case.
Unless there are some abandoned yachts floating around the SF Bay Area, DPRoss Ulbricht probably has ฿500k-614k.
