“Definição de moeda digital decentralizada +como as taxas de criptografia ganham valor”

[…] De qualquer maneira, não há leis que regulem o Bitcoin (ainda) e os Bitcoins sobrevivem no mundo sem a ajuda do atual sistema financeiro. Logo, não cabe a uma autoridade central regular os Bitcoins: cabe às pessoas que os utilizam. Isso faz com que alguns cheguem ao extremo de dizer que os Bitcoins, se bem sucedidos, destruitiram o sistema bancário mundial. […]

O log de transações (“blockchain”) temporariamente dividiu-se em dois logs independentes governados por regras distintas. O site de câmbio de bitcoins Mt.Gox deixou de aceitar novos depósitos de bitcoins brevemente. Cotações de bitcoin caíram 23% para cerca de US$ 37,00,[112][113] retornando ao patamar anterior (cerca de US$ 48,00) após algumas horas.[114]

Hard electronic currency does not have the ability to be disputed or reversed when used. It is nearly impossible to reverse a transaction whether it is justified or not. It is very similar to cash. Advantages of this system include it being cheaper to operate, and transactions are instantaneous. Western Union, KlickEx and Bitcoin are examples of this type of currency.[63]

As transações de bitcoin são processadas dentro da rede peer-to-peer sem a necessidade de um processador financeiro como intermediário entre os participantes da rede. As transações entre as criptomoedas não tem intermediário, portanto, estornos são impossíveis. A carteira bitcoin transmite transações para os nós da rede que continuam a propagação da informação sobre o pagamento pelo resto da rede. Transações corrompidas ou inválidas são rejeitadas por nós da rede. Transações são praticamente gratuitas, exceto pela pequena taxa opcional de transação que serve para dar prioridade ao processamento.[66] A conversão de moedas fiduciárias para bitcoin e vice-versa é feito em sites de câmbio bitcoin.

If you’re just starting out with Ethereum, don’t have a lot of Ether to store or don’t have the money to buy a hardware wallet you can use free software wallets. These wallets are free of charge but are less secure since they are constantly connected to the Internet (and therefore can be hacked).  The top Ethereum wallets are Exodus, Jaxx, MyEtherWallet.

Os pontos que os moradores da cidade recebem no “cidadão ativo” podem ser condicionalmente chamados de “moedas de pseudo-teste”, pois eles podem ser trocados por outra coisa. Quando falamos sobre a moeda criptográfica, isso significa que é uma circulação mais ampla, ao invés de ser estritamente focada.

O bitcoin é uma moeda digital que não está sujeita a regulações de nenhum governo ou banco central. As transações são feitas digitalmente, sem nenhum banco intermediar. Como o dinheiro em espécie, o bitcoin permite que os usuários gastem ou recebam os recursos de forma anônima, ou em grande parte anônima, através da internet. Milhares de computadores no mundo validam transações e adicionam novos bitcoins ao sistema. Existem outras moedas digitais, mas o bitcoin é a mais popular.

Bitcoin está à mercê do próprio computador e os governos podem invadir computadores. Eles podem declarar a transferência pela Internet em uma determinada moeda como ilegal. Eles podem penalizar a conversão de uma moeda de criptografada para uma moeda forte. Os governos têm muitas opções que podem fazer do uso de uma moeda virtual para seu próprio benefício.

While it is difficult to predict the trend of cryptocurrencies in a highly volatile period, it is important to acknowledge the factors behind the decline and reasons as to why the cryptocurrency market is struggling, to evaluate the future trend of the market.

Os chefes de Goldman Sachs e JP Morgan tem criticado o Bitcoin porque consideram que ele é um veículo para fazer fraudes e outros crimes. No entanto, Sir Jon Cunliffe, do Banco da Inglaterra, disse na semana passada que a moeda criptográfica era muito pequena para representar uma ameaça na economia global e acrescentou que os investidores bitcoins tiveram que fazer os seus deveres.

The malware was created in mid-October and November, just as bitcoin began surging to jaw-dropping heights, according to the report, which was published Tuesday. Other cryptocurrencies like ethereum and monero also experienced massive jumps in value in recent months.

These characteristics make Bitcoin fundamentally different from a fiat currency, which is backed by the full faith and credit of its government. Fiat currency issuance is a highly centralized activity supervised by a nation’s central bank. While the bank regulates the amount of currency issued in accordance with its monetary policy objectives, there is theoretically no upper limit to the amount of such currency issuance. In addition, local currency deposits are generally insured against bank failures by a government body. Bitcoin, on the other hand, has no such support mechanisms. The value of a Bitcoin is wholly dependent on what investors are willing to pay for it at a point in time. As well, if a Bitcoin exchange folds up, clients with Bitcoin balances have no recourse to get them back.

Quanto aos computadores que tens aconselho a não minerares pois vais consumir bastante electricidade para obteres poucas moedas, se quiseres podes pesquisar por equipamento especifico que te consuma pouca energia e que traga mais CESC de retorno, contudo convido-te a juntares ao forum e a pesquisar sobre as tuas duvidas bem como pedir ajuda aos outros simpatizantes do Cryptoescudo. http://cryptoescudotalk.com/ ( e o meu nick lá ds650_19 caso precises de alguma ajuda adicional em que eu possa ser util)

Para que a rede gere um bloco novo a cada 10 minutos em média, cada nó separadamente reajusta o nível de dificuldade do criptodesafio a cada duas semanas em resposta a mudanças no poder de processamento coletivo da rede.[72]

DigixDAO is a “decentralized autonomous organization” (DAO) built on top of the Ethereum platform that creates digital tokens backed by gold bars. DigixDAO supports two different tokens. One, which is called the DGD, is only used to give voting power to those who want to decide how to improve the technology. The other, the DGX token, is the actual digital token that’s backed by 1g of gold. The DGD token holders will also receive DGX rewards for holding the tokens long-tern.

Other digital currencies like Litecoin, Ripple, Ethereum and so on aren’t accepted as widely just yet. Things are changing for the better though, with Apple having authorized at least 10 different cryptocurrencies as a viable form of payment on App Store.

F**** miners, buying out hardware and causing shortages at suppiliers. Some douchebag who probably didnt even make a math to see if its profitable for him and makes a mining ring “cus its coool” buys out all GPU’s and then people cant finish their simple gaming builds.

“Cryptocurrency is trying to be the offshore banking system, I think. At least some of the cryptocurrencies. Most of the financial luminaries, I think genuinely, don’t understand what it’s trying to be. Jamie Dimon is an exception. By all accounts, I know people who spoke to him about cryptocurrency four years ago before I was really in the space. He understands it. I think he sees it as a competitor against JPMorgan,” said Paul during an interview with Business Insider.

A Enterprise Ethereum Alliance (EEE), criada em fevereiro de 2017, é composta por 86 empresas, incluindo a JPMorgan e a Microsoft, que apoiam o desenvolvimento do Ethereum. Eles pretendem lidar com questões para as empresas que desejam usar o Ethereum, e seu suporte emprestou credibilidade à plataforma.

“Welfare makes people lazy.” The notion is buried so deep within mainstream political thought that it can often be stated without evidence. It was explicit during the Great Depression, when Franklin D. Roosevelt’s WPA (Works Progress Administration) was nicknamed “We Piddle Around” by his detractors. It was implicit in Bill Clinton’s pledge to “end welfare as we know it.” Even today, it is an intellectual pillar of conservative economic theory, which recommends slashing programs like Medicaid and cash assistance, partly out of a fear that self-reliance atrophies in the face of government assistance.

Ola Adilson deve ir ao site https://www.cryptoescudo.pt/ onde se encontram todos os contactos necessários no entanto tambem pode ir o forum da moeda http://cryptoescudotalk.com e lá tera aceso a poder falr com o Sr. Eugenio Apolo o criador da moeda… abraço

Litecoin – Litecoin is regarded as Bitcoin’s leading rival at present, and it is designed for processing smaller transactions faster. It was founded in October 2011 as “a coin that is silver to Bitcoin’s gold,” according to founder Charles Lee. Unlike the heavy computer horsepower required for Bitcoin mining, Litecoins can be mined by a normal desktop computer. Litecoin’s maximum limit is 84 million – four times Bitcoin’s 21-million limit – and it has a transaction processing time of about 2.5 minutes, about one-fourth that of Bitcoin.

Bitcoin is not going to make government-backed currencies obsolete. But while the system’s virtues, such as anonymity and the lack of bank fees, may not matter much to most consumers, one can envision it being useful in a variety of niche markets (some legal, others not, like recreational drugs). Where anonymity is valuable, where trusted third parties are hard to find or charge high rates, and where persistently high inflation is a problem, it’s possible that bitcoins could in fact flourish as an alternative currency.

Ripple is a real-time global settlement network that offers instant, certain and low-cost international payments. Ripple “enables banks to settle cross-border payments in real time, with end-to-end transparency, and at lower costs.” Released in 2012, Ripple currency has a market capitalization of $1.26 billion. Ripple’s consensus ledger — its method of conformation — doesn’t need mining, a feature that deviates from bitcoin and altcoins. Since Ripple’s structure doesn’t require mining, it reduces the usage of computing power, and minimizes network latency. Ripple believes that ‘distributing value is a powerful way to incentivize certain behaviors’ and thus currently plans to distribute XRP primarily “through business development deals, incentives to liquidity providers who offer tighter spreads for payments, and selling XRP to institutional buyers interested in investing in XRP.” 

Em 1998, Wei Dai publicou a descrição do “Dinheiro B”, um sistema eletrônico e anônimo de pagamento.[18] Pouco depois, Nick Szabo criou o “Bit Gold”.[19] Assim como o bitcoin e outras criptomoedas que o seguiram, Bit Gold era um sistema de moeda eletrônico que exigia seus usuários completarem uma função de prova de trabalho, com as soluções sendo criptograficamente computadas e publicadas.

The cryptocurrency market rebounded after dropping below $344 billion, losing over $100 billion within the past week. Although major cryptocurrencies like Ethereum have recorded gains over the past 24 hours, most cryptocurrencies have started to fall again.

The thing that bothers me about blockchain is that I don’t see how it can economically reach large enough scale to be practical for any significant fraction of transactions. Ethereum might be fine for real estate transactions, but we won’t be using it to buy a pack of gum.

Ao longo dos últimos 5 mil anos, o homem tem experimentado inúmeras formas de moeda. Cada uma, por sua vez, desaparece, eventualmente, assim como as suas deficiências tornam-se evidentes. O dinheiro de papel parece ser o próximo na linha de extinção, e com razão. A única forma de moeda que sempre se manteve ambos válidos e em uso contínuo tem sido metais preciosos. À medida que avançamos em direção ao possível fim da moeda-papel, mais do que nunca, o ouro, mantém o seu brilho como o paraíso eterno seguro para a preservação da riqueza.

Blockchains are secure by design and are an example of a distributed computing system with high Byzantine fault tolerance. Decentralized consensus has therefore been achieved with a blockchain.[20] It solves the double spending problem without the need of a trusted authority or central server.
