O que é BitCoin?

Talvez você já tenha ouvido falar de BitCoin – ela quer sacodir toda a economia global. É um tipo de moeda online – uma alternativa para dólares, euros e reais. Bem, o que isso significa? É complicado, mas nós iremos explicar com mais detalhes.
Bitcoin é uma moeda virtual…
BitCoin não é dinheiro de verdade. É uma “unidade monetária” online – tokens virtuais que podem ser trocados por bens e serviços em lugares que o aceitam, da mesma maneira como você trocaria um Real por um pão na chapa.
…com aspirações enormes…
Em seu manifesto do YouTube, os criadores do BitCoin dizem que eles irão revolucionar as finanças globais da mesma maneira que a web mudou a indústria editorial. Uma meta bastante ambiciosa, tentar ser uma moeda global do mesmo jeito que (ou para substituir) o dólar. Nas atuais circunstâncias, é o sonho mais improvável, dentre todos os sonhos praticamente inalcançáveis.
…que é trocada via P2P…
Quando você preenche um cheque e entrega para uma amiga, o dinheiro da sua conta é retirado do seu banco e então transferido para o banco dela, e então ela (talvez) faça um saque em dinheiro. Com BitCoin não há intermediários (a não ser os próprios utilizadores da rede). O dinheiro passa direto de você para quem quer que seja, através do sistema P2P do BitCoin, sem agências intermediárias repassando as fichas.
…e gerada por seus usuários…
É aqui que começa a ficar um pouco estranho! Diferente de unidades monetárias tradicionais, que são baseadas em alguma coisa, (seja ouro, prata, ou um banco central), BitCoins são geradas do nada. Através de um processo chamado “mineração,” um app fica no seu computador e lentamente – bem lentamente – cria novas BitCoins em troca de fornecer poder computacional para processar as transações. Quando uma nova fornada de moedas está pronta, elas são distribuídas de acordo com a probabilidade de quem teve o maior poder computacional no processo de mineração. O sistema é feito para que não mais de 21 milhões de BitCoins existam – então o processo de mineração será cada vez menos rentável com o passar do tempo, conforme mais pessoas se cadastrem. Isso faz com que o sistema inteiro seja mais vantajoso para early adopters.
…para ser gasta nos poucos lugares onde BitCoins são aceitas…
Não são muitos os lugares que aceitam BitCoins no momento, diferente de moedas tradicionais. Mas os incentivos para que pequenos negócios comecem a usá-las não são ruins – é gratuito para usar, e não existem taxas de transação. No momento você pode comprar serviços de um web designer, jogos independentes para PC, bijuterias artesanais, armas e, cada vez mais, drogas ilegais.
…ou convertido em dinheiro de verdade…
Assim como você pode trocar ienes por dólares, você pode trocar suas BitCoins com outros usuários por diferentes moedas do “mundo real”. E no momento, o BitCoin está em alta! Agora, mesmo, um BitCoin vale U$7.5. Nada mal.
…e não tem nada parecido no Brasil até o momento.
Algumas outras tentativas de moeda eletrônica chegaram aos Estados Unidos e Europa, como o DigiCashLiberty Dolar e e-gold, mas não obtiveram muito sucesso; talvez por serem centralizadas, ou talvez porque o meio de obtê-las era trocando por dinheiro real – e algumas até enfrentam acusações de fraude. Até o momento, não encontrei nenhum relato de iniciativas de Moeda Online no Brasil, ou de alguma das citadas ter chegado por aqui. Vocês conhecem? E, mais importante, apostariam dinheiro de verdade em dinheiro de mentira que não seja o consagrado ouro de World of Warcraft?

    WHAT IS BITAIR: Today, there is no change in payment solutions that is recognized to effectively and efficiently handle the rapid economic growth within the market. A majority of consumers are facing difficulties regarding payment methods. Money transfer charges are increasing and transaction times are longer than before. The amount of a single transaction payment is also limited. A new payment system would allow firms, individuals, governments and other economic agents to transfer money on a daily basis without such inconveniences.
    Therefore, Bitair is building a different payment system. It is designed to facilitate on-demand payment. It is secure, has lower fees than traditional payment methods, faster access with no limitation of the amount used to buy any travel & tourism services.

    TEAM: Tommy Barron Co-founder & CEO A blockchain entrepreneur, An industrial Engineer and Enterprise Strategic Consultant specializing in payment system and product design. 6 other members with over 7 years experience in Blockchain.
    Transparency and immutability: Changes to public blockchains are publicly viewable by all parties creating transparency, and all transactions are immutable, meaning they cannot be altered or deleted or recovered.

    CURRENT STATUS: They have more two branches in Indonesia and Philippine operating travel and tourism activities of outbound and inbound services. Asia Pacific Travel PTY Group forecasts to generate strong growth of revenue (over $ 1 billion) in 2017 related to airlines booking services.
    Large volume of passengers have made payment within Bitair system and our team has also conducted extensive research into payment options and 65% of questioned passenger said "YES" to paying by bitair instead of other methods: Visa, cash, bank transfer, etc.

  6. Cryptonicles put together a how-to-guide to begin mining your own coins through Stake United staking pool - only started in mid November. Some guy just doubled his $500 dollar investment on an aggressive mining coin... in 3 days.... ………..

    http://www.cryptonicles.com/posts/a-step-by-step-how-to-crypto-guide-stake-uniteds-proof-of-stake-mining-pool-regi-17126774

    Some coins pay out 1% per day, others up to 20% per day in the pool because its 10x stronger than if you mined yourself.

    A very unique way to build up your wealth portfolio on the blockchain using community mining power.

    He’s also written a very lovely piece for those not lucky enough to have rich parents.

    Really eye opening - check it out.

    Investing is so creative now.

    Looking forward to more from this guy.

  17. Look at the way my acquaintance Wesley Virgin's report begins in this shocking and controversial video.

    You see, Wesley was in the military-and soon after leaving-he found hidden, "self mind control" tactics that the government and others used to get anything they want.

    THESE are the same secrets lots of celebrities (especially those who "come out of nothing") and elite business people used to become wealthy and successful.

    You've heard that you use less than 10% of your brain.

    Mostly, that's because most of your brain's power is UNTAPPED.

    Perhaps this thought has even taken place INSIDE your own head... as it did in my good friend Wesley Virgin's head 7 years back, while driving a non-registered, beat-up bucket of a car with a suspended license and $3.20 in his pocket.

    "I'm very fed up with living check to check! When will I finally make it?"

    You've taken part in those types of conversations, right?

    Your very own success story is going to be written. Go and take a leap of faith in YOURSELF.

    WATCH WESLEY SPEAK NOW
