Bitcoin Exchange Market

When will exchanges offer the option to trade bits or millibits instead of full bitcoins

At some point it will be more appealing to get 100bits for a dollar or 1 millibit

You pussies scared of a few decimal places?

You need to pay someone 0.0000398 btc "Four zero(s) three nine eight"
You need to pay someone 0.40398 "Point four zero three nine eight"
You need to pay someone 40398.0 "Fourty thousand ..."

This is why I am super bullish on Bitcoin!

The amount of people asking if it's the right time to sell bitcoin is too damn high!! So let me post my view on bitcoin. Bitcoin is still in a bull market if you look at the big picture. From a few cents in 2009 to $565 now in june 2014, that is a massive gain!! Is it over? NO!
This could be the biggest bull market of the century! After the last bubble in nov/dec bitcoin got really hyped in the media. Investors/venture capitalists were buying and investing. From january till may/june it was bad news all day about bitcoin. People forget the essence of bitcoin and don't embrace all the good news.
Just to name a few
Adoption is happening but you guys just don't realize it yet. You will soon. Because something big is coming! The things above is nothing compared what is about to come.
Don't forget about this. The investors/venture capitalists/developers/etc. who learned about bitcoin last bubble are working behind the scenes. They are invested heavily in bitcoin. They will innovate to make bitcoin better and stronger. The next bubble will come as a surprise. You don't know when and how long it will last.
Catalysts for bitcoin to rise to the moon:
2014-2019
Input:BitcoinOdyssey, Bitcoinula
2019-....
Wall street got involved. This will lead to massive innovation for user adoption. Bitcoin can be used as currency but for other stuff aswell. I don't know what exactly. But bitcoin is 'smart money', there will be 100 or more ways to use bitcoin. The average joe does not need to know how bitcoin works. The average joe should be surprised when you say ? 'They use satoshi's to make this process possible'.
You guys now are bashing early adopters why they only bought 300 bitcoin and not thousands... let me tell you this. There is a possibility that bitcoin will move to millibit as a standard. And there is also a posibility that 1 millibit will be trading for $565,00. Seems impossible right? S curve growth of bitcoin is still in its early stage. The vertical stage will be expected within a few years. Daily gain of 1-3% for months making bitcoin growing hundred to thousands % yearly!!
My friends, join the party. Buy and HODL. the future is bright. ANything under $1000 is cheap, between $1000 - $5000 is oke to buy. $5000- $50000 is HODL and between $50000 and $500000 HODL and SPEND.
CHeers!
P.S. Input is appreciated and I am also open for discussion. I am very positive but it does not mean I think bitcoin is perfect. There will be bumps down the road, the road........ to the MOON!!!
Downvote if you think bitcoin dies within 5 years.

Let China detach as we did with Gox

Make your own conclusion.
Point of view 1: http://bitcoincharts.com/charts/volumepie/ CNY, 7% ? USD 87% ? edit: this is a % of the volume, not a % of the total money invested
Point of view 2: An other view: https://bitcoinaverage.com/#USD-millibit USD volume: 78%, CNY volume: 13%. edit: same here

At the moment it seem we are dumping more than them ? Are they really driving the price ? edit: this is not including Huobi & OKCoin volumes.

I'm not trading, but this looking weird to me.
edit As said above I'm not a trading and my understanding in this domain is limited. Please correct me if I'm doing bad.
From my point of view, something isn't logic and sound wrong. I'm not looking into the daily volume because I think it's not revealant enough. 1 person investing $1k, to buy/sell only one time, will generate less volume than 20 persons, investing $25, buying/selling 20 times. But this 1 person invested more money than the 20 others together. So I'm watching into the depth. It seem a lot of peoples think Huobi are faking the data, but let's suppose they don't. I made 2 small graphs (only Bitstamp vs Huobi | $1 = 6.25 CNY): http://imgur.com/X5NWmWu http://imgur.com/pQHr7tw We seem to have more buy power than them on the short term (hard to say on the long term as I can't find the whole Huobi depth). We have to sell more than them to get on the same level ? I just don't understand how they can drive the price so strongly, and why we are falling in this.
edit2 quoting da_unique
Those Chinese also do not run full node wallets or miners, if this source is correct: https://blockchain.info/nodes-globe As long as huobi and the likes fakes their volume, and people keep abusing this fud to earn a quick buck, I guess we will be goxed for the coming 10 years.

Thoughts on the current state of Bitcoin from someone who participates in much of the ecosystem [and tipping thread ;) ]

Hey guys,
So this is something I've been looking at for a while now, and kind of seeing some things die and other things be born. Some things are getting easier, and other things getting more difficult. I want to take this time to outline the last few months and how my sentiment is reflected towards the market. I have to say, the market generally matches how my "emotions" playout towards the ecosystem as a whole.
I'll outline just a few short things on both the bearish and the bullish sides of my sentiment, even if things don't effect the overall sentiment much (at least according to most traders and people) I'd like to point them out because I view them as notable.
Some of the not so good things that have been happening:
Anyway, in many respects it feels like a lot of the bitcoin ecosystem is dying, and maybe we should all panic, cry, and shit our pants, but a few things haven't been going badly, and in fact, I'm looking optimistic that the next time a surge of new users enters the market for whatever reason, there will be a much more developed and kind ecosystem to take part of. No one is going to be touting the next 5 second confirmation coin, no more of the ubiquitous "investment" opportunities that await the uninitiated.
Other than my love for bitcoin in general, this is what makes me not panic sell, and what keeps me optimistic about the bitcoin future:
Alright guys, thats my sentiment overview, and I hope it wasn't tl;dr for most of you. But one last thing I want to point out in terms of user growth. We need to break out of our comfort zone. We need to help people get into it. That btctipping dude? He has the right idea, except, it does kinda feel like he's promoting his own website? I dunno? Anyway, Changetip some newbies. Just the other day in the reddit lounge I tipped a guy a coffee, and he then said "Man that was evil, now I have to spend the next hour learning all about bitcoin"... who knows, maybe his sentiment that the media helped paint is one shade lighter now just from a a couple millibit tip. You can do that too, and I'm here to help you get started. I've got some millibits to give away, give me some awesome feedback, criticism or build your own thoughts on this thread. I tip you, then you go pay it forward. Lets do this!!!

Suggestion for useful subunit in today's 10K+ world

Hello Bitcoiners,
(This is focused on the US dollar) - For those of us who believe in Bitcoin as a currency, as an exchange convenience, we have used subunits ever since a single bitcoin reached certain heights. As the price approached $1,000, the millibitcoin (0.001 BTC) became the closest to a US dollar and thus the most reasonable way to talk about everyday prices in BTC. For example, when I went to my favorite diner back in the day, a typical meal was 60 or so millibits. Those days are long gone.
But as of writing, a single millibit is just under $19.
The next unit down I've seen in all Bitcoin articles is the microbit - currently worth just under 2 pennies. Handy for talking about buying lollipops but not really for things like a tank of gas.
A now-obsolete French double prefix was the decimilli-, 10-4, shortened to "dimi-".
A "dimibitcoin" is today worth about $1.90.
So I suggest the use of the dimibit as a subunit of a bitcoin. Thoughts?

Keeping it simple. Bitcoin units + terminology.

I've read so much about this that my brain hurts. I am NOT numbers person so I unfortunately have very little to offer a constructive conversation.
But I do know (like most here do) that bitcoin has a long way to go until it is easy enough for average Joe and grandma to use. I've spoken with hundreds of people about bitcoin and have taken many of them down the rabbit hole of explanation. When it gets into 'divisible.. decimals... millibits...' people's eyes start to glaze over. Yes - that is due to habit of our current system and dollars/coins (in the US) - but it is also due to the fact that .0000007 of something for something as compared to .000007 of something for something is craziness. And until the units + terminology is so simple and so user-friendly, people will keep it at arms length. That is just the way it is.
I understand the mathematical need for exchanges / coding that must factor in decimal places and/or use a certain unit of account for computation. But I more understand the fact that people (like me) are stupid and lazy.
I want my grandma to use bitcoin like she can send an email. But it is going to start with what in the world she's dealing with and how much it's costing her in dollars.
So to push the envelope - what is the latest and most agreed upon nomenclature and size of a BTC on down. Can someone bulletpoint it for me?
Simple. Simple. Simple.

Why wallets should have built in price conversion

We periodically see posts suggesting that "1 Bitcoin" at $1000, $2000, $3000, $4000 sounds too expensive, and results in an off-putting pack of zeros after the decimal point when purchasing your kombucha.
Folks then plead for the community to finally switch to millibits or to microbits but call them "bits" for short. Arguments tediously play out again about what the best unit is, and what the best thing to call it, or whether we should switch to the tonal number system, or whether people should just get over themselves stop being irrationally uncomfortable with paying .000222 bitcoin for a cup of coffee.
After that, everyone goes back to measuring everything in 100,000,000 satoshi units. Here is a post from 4 years ago called It's bits which was submitted about 4 years ago.
And all of that ignores the fact that tomorrow the cup of coffee is likely to have a different price, measured in bitcoin. Which is a problem! Critics have rightly observed that no one would dare take out a large loan in a deflating currency, and it would be psychologically difficult to rejoice over your annual pay cut in quite the same way you enjoy getting a raise.
People think of the "unit of account" function as being central to the definition of currency, but Satoshi didn't choose that as a design goal. Instead, he gave us this fixed issuance curve and let the price chips fall where they may. It's part of what makes bitcoin more like a "base metal as scarce as gold", that is to say more like a commodity and less like a currency.
Sure, volatility has gone down in the last 8 years, but what you really want from a unit of account is no volatility at all. We would have some measurement of value that is stable over time -- let's call it the Jolly for making the point. A meal at a fast food place should probably cost 10 to 100 Jollies. A meal at a nice restaurant might be 10 to 1000 Jollies. Something like that. That's a range of quantity of value that people seem to find convenient to work with and think about, if you look around at a lot of national currencies.
We don't have the Jolly right now, and getting global consensus on a definition of one would be tough. Maybe some day.
In the mean time, what makes sense to use as a unit of account is your local good-enough fiat currency unit. Mind you, we are not going to use the filthy government money itself, just borrow the unit as a measurement of value. The unit has merit, is free to use, and has no downsides that I can see. (If your local currency is unstable, you could just use the Dollar, Euro, Yen, Yuan, Pound or whatever relatively stable currency is most popular where you are.)
It doesn't make sense to use Bitcoin as a unit of account, and nobody really does it because the people who have tried have been burned. So when you think of "1 Bitcoin" think of it more like you are saying "1 Kilogram of the commodity called bitcoin." Buy your coffee with bitcoin, measured in dollars. Take out your loan in euros, payable with Bitcoin.
But here's the thing, wallets need to support this way of thinking. They need to measure bitcoin balances and amount you are sending or requesting in regional units that the user chooses. To support that, they are going to need to know the exchange rate. Exchanges, Winkelvii and others could offer web service calls or RSS feeds of whatever, and users could choose the sources they prefer. Wallets could sanity check the sources and provide alarms when sources are too far apart, or change a lot in a short period of time. They should also print the exchange rate prominently so that the user can also check it for sanity.
TLDR: Wallets should allow the user to select a regional currency, and their balances and transactions should display measurements in that unit of account.

Hello World! This is my message for you from the future. I hope this survives the time transfer and lands in the correct timeline. Just a few checkpoints to make sure this message arrived to the correct timeline.

It is the year 2035. First question what I would have wanted ask in 2017, if I ever got the opportunity to communicate into the future would be: what is the price of bitcoin? Well I would of course want to know the price measured in US dollars or Euros or some other fiat currency. What if I told you the fiat currency value hasn’t been relevant for the last 10 years. A draft beer costs about 2.0-2.5 satoshis (we call them stoshis), A meal in a restaurant around 6-8 stoshis, A good quality Pizza 5 stoshis. Cadrone transport 0.01 - 0.05 stoshi / km. I hope this helps you get the idea of the purchasing power we are talking about. I can briefly tell you about how the massive increase of bitcoins purchasing power rose so fast even the most optimistic bitcoin believers were surprised. There are many factors and events that all had an effect on the rising demand for bitcoins. 2016 after the most tech savvy liberal minded people had bought into bitcoin things started to happen. 2017 was the year when earlies (early adopters) started investing into bitcoin. (I know it’s funny we all thought in 2016-2017 that early adopters had been ones having bitcoin in the first 5 years after it was created). sidenote: Companies who have started working with bitcoin will see their stock value rise which will push more and more businesses to adopt bitcoin. The demand was huge in Japan, but no one really knew the real reason for Japan recognizing bitcoin as a legal method of payment (so absurd, bitcoin doesn’t a permission). I remember people speculating it was because Japan’s economy was terrible and the % of old population wasn’t decreasing. And yes people speculated correctly. After the famous, Tokyo based, bitcoin exchange called Mt.Gox collapsed in 2014 Japanese authorities had to look into what bitcoin was. It took sometime and eventually someone with enough political influence realized the potential. Japan had to play this whole thing smart, if they started buying bitcoin publicly the global FOMO (fear of missing out) would push the price quickly out of their reach and their Japanese Yen would turn into goat shit. So instead they started out by doing small things like legitimizing bitcoin as a payment method, Government services started accepting bitcoin, small amounts of taxes payable with bitcoins and all at the same time trying to buy as much bitcoins as possible without moving the price too much. Of course everyone knows secrets always spill out, especially government secrets. Soon South Korea was “legitimizing bitcoin” and it didn’t stop there. It started to spread. Some governments tried to stop it (Usa, Russia, Some European countries, India) but banning and/or over regulating it turned out to be useless. So what does a desperate government and banking system do when they have the ability to print unlimited amounts of fiat currencies and are losing their power to people. They print money and try to buy all the bitcoins up. Well I can tell you it didn’t work or well it worked in a nice way which made the unfair system of fiat currencies irrelevant. Some countries figured the potential of bitcoin at the same time as Japan and started doing exactly the same as Japan. Making their citizens aware of bitcoin and buying up bitcoin without signaling a panic buy for the others. Switzerland for example started selling bitcoins to their citizens by Swiss Federal Railways ticket machines. How smart is that? China on the other hand banned and unbanned bitcoin a lot in 2014-2015 timeframe. Then the PBOC “cracked” down on the Chinese exchanges, this was all because china wanted to make bitcoin look more attractive for the investors. China had already been buying bitcoins from 2014, small amounts without raising the price too much. This was a long term investment for china which paid off during the collapse of the US dollar and yuan. The second question that probably would interest me in the past (one of the reasons I postponed investing into bitcoin until the beginning of the year 2018) would be the “The Big Scaling Debate” which really looked at the time as fierce debating but it was really just a power struggle to control bitcoin. Segregated Witness was activated and looking from where I am currently standing it was the best technical solution which everyone actually agreed on but some people where blocking it by making up nonsense and stalling the progress. Funny thing is that once actually big chip manufacturers got interested in ASIC manufacturing and bitcoin mining lots of the bad acting bitcoin mining hardware companies found themselves out of business. We all know who we are talking about. For the technically literate I can’t offer much information from the present because it has gone over my understanding. Everything is connected to the bitcoin blockchain. Protocol upgrades made it possible to build layers on top of layers all secured by the hashing power of the bitcoin blockchain. My car’s private key is stored on a layer of the blockchain, my voting password is also there, I have a private key for my identity and the private keys for my kids identities as well as their medical record private keys. How has the planet changed? We finally reached a stage a few years ago where we got the future of planet earth on a level where it will be sustainable to live in as long as the sun doesn’t burn us down. Bitcoin played a big part in this. Deflationary currency has strange effects, nobody on earth produces crap anymore, meaning no cheap electronics that last only a few years, no plastic bags in stores, no cheap clothes that will last only a few times in a washing machine. Everything and I mean it when I say everything is made with high quality materials and products are made to last long. The demand for high quality long lasting items came from the people. Why would you use a few millibits which grew in purchase power every year to buy some crappy headphones that would last 1 year if you were lucky. If they were going to use their precious millibits they wanted something high quality which would last. Also 95% of the worlds energy is from renewable energy sources, when big bitcoin mining operations started struggling with their profit margins they looked at small bitcoin mining operations who had minimized the cost of electricity by using solar panels and hydropower. Funny how bitcoin mining operations trying to be more profitable boosted the use of renewable energy sources, ok I must add that the death of the petrodollar helped also. Electricity isn’t produced anymore for the need of humans it is produced to power the bitcoin mining facilities and we just use the leftover energy which is more than enough. You are currently in the phase of one of the first altcoin bubbles. These bubbles are part of the bitcoin learning curve for people. People tend to forget what bitcoin is about and then seek high % profits from altcoins. This will happen a few times more in history and most of the altcoins will slowly die away and be replaced by new “innovative” ideas. In the upcoming years the value that poured into altcoins will move into bitcoin. Some of the most biggest alts with minor use cases will survive for longer but their ideas will be built and secured properly on different layers of the bitcoin protocol. What do I regret the most? My biggest regret was not buying bitcoins when I first heard of them, also I regret buying a sailboat with 50% of my small bitcoin stash in 2019. Also I regret not getting into mining when it was still profitable for an average person in 2019. But I am happy I hodled the rest. (yes the hodl meme has survived all these years)
One cool thing we discovered besides sending information “back in time” is sending payments to the future. I will be generating the private key for the following bitcoin address on November 20th 2035. I will also login to reddit with the account Blazewhale to celebrate with those of you who are still here. Happy Hodling, price discovery is a bitch.

ELI20: What would it take to change the "standard" denomination to mBits?

I know this topic has been beaten to death a bit, so sorry about that. But, like many others, changing most public displays of bitcoin value to millibits is an idea that makes a ton of sense to me, if only from the psychological angle. There are simply too many people who still believe that bitcoin is "too expensive" for them right now.
So my question is, what needs to actually happen for this to become a reality? Would it come in the form of a suggestion by the foundation? Or would one of the popular exchanges start doing it and initiate a trickle-down effect? Or something else entirely?
Suffice it to say, in my opinion a $.39 millibit just has a better public face than the $390 bitcoin.

/r/oBitcoin FAQ - Novatos por favor leiam

Bem vindo ao /oBitcoin FAQ fixada

O texto que se encontra aqui foi desenvolvido por Mtzrkov e outros em Github.com/btcbrdev/oBitcoin e está em domínio público para ser usado livremente por qualquer um.

O que é bitcoin?

Bitcoin (BTC ou XBT) é o primeiro e mais importante dinheiro eletrônico sem autoridade central, baseado numa tecnologia open-source inédita chamada Blockchain, que foi desenvolvida por Satoshi Nakamoto em janeiro de 2009. Essa tecnologia permite a criação de um "banco de dados" confiável P2P (ponto-a-ponto), o que abre caminho para muitos tipos de inovação, sendo uma delas o próprio bitcoin e outras como contratos descentralizados, por exemplo.
Nota: normalmente emprega-se "Bitcoin" em maiúsculo para se referir ao protocolo (baseado na tecnologia Blockchain) e em minúsculo "bitcoin" para se referir a uma unidade da moeda.
O Bitcoin, além de um bem digital, pode ser considerado também um sistema de pagamento, totalmente independente de qualquer sistema já existente, como cartões de crédito, Paypal, bancos e outros. Sua capacidade atual estimada é de 7 transações por segundo, mas essa capacidade pode ser aumentada com o passar do tempo se houver necessidade. Por ser puramente digital e distribuído, o Bitcoin funciona 24/7 e tem alcance mundial, além de ter locais especializados de troca pela moeda local (chamados exchange) nas principais cidades do mundo.
A segurança da rede do Bitcoin, ou seja, o que garante que não existirá um chamado "gasto duplo" do mesmo dinheiro, é o consenso da rede P2P feito pela validação das transações por parte dos mineradores. Para que um minerador consiga incluir um bloco válido na rede, ele precisa utilizar um grande poder computacional. O processo de mineração consiste na realização de cálculos matemáticos para a seleção de quais transações válidas serão incluídas no próximo novo bloco do Blockchain, excluindo aquelas que tiveram uma tentativa de "gasto duplo" naquele período. Cada nó da rede, além dos mineradores, também é capaz de verificar a validade das transações incluídas no bloco. É nesse processo também que aparecem os "bitcoins ainda não descobertos". A distribuição dos bitcoins é feita de forma previsível, tendo uma queda de recompensa pela metade de 4 em 4 anos. Serão encontrados no máximo 21 milhões de unidades da moeda.

Quanto vale um bitcoin?

O preço de mercado de um bitcoin é determinado através da lei da oferta e da procura, portanto estando sujeito a variações de preço por causa de acontecimentos políticos e econômicos (como desvalorização e inflação de moedas estatais, conflitos, maior demanda por Bitcoin etc).
Assim como nas moedas estatais, o preço do bitcoin varia e pode ser diferente dependendo do lugar em que for negociado.
Se você for comprar dólares no Brasil, você terá que procurar uma casa de câmbio que poderá ter a cotação de R$ 3,00 por dólar, por exemplo. Caso vá a outra casa de câmbio, você poderá notar que o preço poderá ser ligeiramente diferente, além das taxas também variarem. Com o Bitcoin não é diferente. Essa variação entre as exchanges (nome comumente usado para se refererir aos locais de compra e venda de bitcoin) são equilibradas pelo mercado através de operações de arbitragem (comprar num lugar mais barato e vender num mais caro).
Para se ter uma ideia do preço médio do bitcoin, você pode dar uma olhada em sites como os que seguem:
Para um gráfico do preço ao longo do tempo, acesse:

Volatilidade

Por ser uma moeda ainda muito recente (inventada em jan/2009) e ainda não muito utilizada, seu preço de mercado ainda é muito volátil. Isso faz do bitcoin um investimento de risco atualmente. O preço tende a ficar mais estável ao longo do tempo, quando o mercado puder definir com mais exatidão seu "preço real". As oscilações também tendem a diminuir conforme o seu market cap (quantidade de moedas x preço) aumentar. Hoje (2015) o market cap do bitcoin é de US$ 3 bi, o que pode ser considerado pouco se comparado ao valor de algumas empresas como a Dell (US$ 24 bi) ou ainda de outras commodities como o ouro (US$ 2.600 bi).

Como obter bitcoins?

O bitcoin é um bem digital e assim como outros bens, pode ser adquirido de diversas formas:

1. Negociação direta (P2P / pessoa a pessoa)

Uma das maneiras mais baratas de se negociar bitcoins, porque não tem taxas, é comprando diretamente de outras pessoas que já possuem a moeda. As duas partes chegam a um acordo de preço e a troca é feita. Geralmente quem tem menos reputação entrega o bitcoin ou a moeda local primeiro.
Por ser uma maneira relativamente arriscada, pois não há um mediador para casos de descumprimento de uma das partes, a reputação de alguém deve ser muito considerada. Exemplo: prefira negociar com alguém do seu círculo de amizades (rede de confiança), alguém que você confie muito como familiares e amigos, ou por uma indicação (amigo de amigo). Se a outra parte tem uma reputação duvidosa, prefira negociar aos poucos (divida os valores em várias partes menores e vá trocando aos poucos).
Algumas ferramentas auxiliam nesse processo de reputação e rede de confiança, sendo elas:

2. Negociação indireta (com intermediário)

Outra forma de se negociar bitcoins (e essa provavelmente é a maneira mais conveniente, embora não seja a mais barata) é utilizando um intermediário que viabilize a compra e venda de bitcoins entre pessoas interessadas. Esses intermediários são as "corretoras" ou "bolsas" de bitcoins (mais conhecidas por exchanges).
Essas corretoras fornecem um serviço de intermediação entre compradores e vendedores de bitcoin, cobrando uma taxa para tal. Por causa disso o bitcoin nas corretoras tem um preço final um pouco mais alto do que se fosse comprar de outras maneiras, mas devido ao altíssimo volume, uma operação pode ser realizada instantaneamente.
Além de usar exchanges, você também pode encontrar um intermediário na relação P2P, tornando-a mais segura. Exemplo: um amigo em comum, que pode levar uma comissão previamente combinada para intermediar as duas partes.
Você pode conferir uma lista de corretoras no ExchangeWar. Algumas das principais corretoras brasileiras são:

Onde gastar bitcoins?

Hoje é virtualmente possível gastar os bitcoins em qualquer lugar, usando algum intermediário para trocá-los imediatamente sob demanda por alguma moeda local, como numa exchange ou com serviços como Neteller, Xapo ou Gyft.
Alguns locais porém já aceitam a moeda digital diretamente, como é o caso da Microsoft, Dell e Overstock, além de inúmeras outras ao redor do mundo.
Confira uma lista com mais de 100 mil lugares que já aceitam diretamente o bitcoin em SpendBitcoins ou no CoinMap.
Segue algumas listas de locais que aceitam bitcoin no Brasil:

Como minerar bitcoins?

Para minerar bitcoins você precisa executar um software em um computador especializado (ASIC) que possa realizar uma grande quantidade de operações matemáticas demandada pelo sistema de consenso P2P do bitcoin.
Logo após a criação do Bitcoin em 2009, era possível e rentável minerar bitcoins utilizando o processamento de computadores pessoais (através de simples processadores e placas de vídeo), mas com o tempo essa atividade deixou de ser rentável e tornou-se praticamente impossível para tais máquinas. Isso aconteceu pois o interesse no Bitcoin aumentou muito, trazendo assim mais pessoas para a mineração e impulsionando uma corrida por maior quantidade de processamento. Com o avanço da tecnologia e o aumento do interesse por Bitcoin, mais poder de processamento foi adicionado à rede Bitcoin e isso resultou em um aumento da dificuldade para se encontrar novos Blocos.
Essa é uma característica do protocolo Bitcoin: quanto maior o poder de processamento da rede, maior a dificuldade para se minerar bitcoins - ou seja, maior a dificuldade para se descobrir novos Blocos. Um bloco é um arquivo que possui uma identificação (data, hora e informações genéricas) e um registro das transações (movimentação de bitcoins entre endereços) mais recentes. Resumidamente, os mineradores são uma forma de manter a rede Bitcoin segura e operante, algo que demanda muito poder de processamento (o que torna inviável o uso computadores de propósito geral para tal fim) e que, como retribuição por essa tarefa importante, gera uma recompensa em bitcoins pelo trabalho.
Todas as transações, ou seja, as movimentações em bitcoins realizadas entre endereços (carteiras), são anônimas pois se caracterizam como uma transferência de fundos de um endereço Bitcoin para outro, que, embora tenham relação indireta com pessoas reais, não possuem uma relação direta. Ou seja, não é possível dizer com absoluta certeza que determinada pessoa é detentora de um endereço a menos que ela diga isso em algum lugar - o que torna o Bitcoin algo pseudônimo, não anônimo (você é anônimo apenas se quiser e tiver conhecimentos para tal). Todas as transações da história da rede Bitcoin são públicas e podem ser conferidas em sites como o Blockchain Info.
Então...é impossível minerar hoje em dia num PC comum ou notebook? Sim, mas não é lucrativo. Para isso existem os ASICs (Circuitos Integrados de Aplicação Específica, em inglês Application Specific Integrated Circuits), hardwares específicos para mineração. Há uma lista na Bitcoin Wiki, em inglês, onde estão listados todos os ASICs disponíveis no mercado e também placas gráficas e processadores. É importante notar que embora seja possível minerar bitcoins, não é algo recomendado aos brasileiros, uma vez que o equipamento é caro, importado e possui taxas de importação - além da energia elétrica brasileira, que inviabiliza totalmente o processo.

Testers needed: Bitcoin wallet for Chrome/ChromeOS

This is a preview of Happynine, a BIP 0032 Bitcoin wallet. Before you skip to the bottom of this post and install, please be warned that this is an early version that has plenty of bugs and missing features. I haven't done a very good job of documenting it, either, but I'd love to answer questions here about how to use it.
My first public call for testers is here on /chromeos. This is because you're the audience I wrote this app for. If you're into Bitcoin, you've heard the story over and over of Windows users wondering why their Bitcoin suddenly disappeared from their machines. This is the teachable moment when they really deeply realize the impact of a poor decision to entrust money to a malware-infested OS like Windows. ChromeOS is a much better platform for a use case like Bitcoin storage. (I know you guys already knew this.)
If you do install Happynine, I recommend sending a millibit or so to the wallet you create, then try sending a fraction of it back to your other wallet. So far I've had 100% success in real transactions with the app, but if you find a bug I don't want it to be with very much of your bitcoin. If you follow my advice to start small with 1 mBTC, at worst you'll lose about 60 cents (at today's USD exchange rates). Again, so far I have not experienced lost or misdirected transactions with the app, but that doesn't mean there aren't undiscovered bugs.
Have I sufficiently scared away everyone but the risk seekers? Good! Please read the README, install the app, inspect the source code, build it yourself, file bugs, and ask general questions here on this thread. Thanks in advance for your help and support!
Edit: almost forgot to mention! Since installing Crouton a week and a half ago, I've been doing development exclusively on my Toshiba Chromebook. So I can truthfully say that this Bitcoin wallet is developed for Chromebooks on Chromebooks.

Millibit campaign

Good morning bitfans!
What if we start a big campaign to change the default unit "Bitcoin" to "Millibit" in all over the Internet? Stop to say "Bitcoin" and start to say about "Millibit"... It's much easier nowdays! Every site, exchange, everything should work with millibit now! Let's do it.
I'll start this changing my app Bitcoin Paranoid to "millibit" as default. When I finish I post here in this thread.

Even if bitcoin was a ponzi scheme, with malicious intent.........

I just want to point out that even if bitcoin was a ponzi scheme (a reality that only comes true if the price tanks, until it rises again due to demand), any user can hedge their position all the way down to fractions of a millibit by selling futures, or options when they become available.
The result is that the value of their bitcoin holdings will remain the same, their purchasing power remains the same, and they will still be able to transact and buy things with bitcoin. Given the same demand the exchange rate of bitcoin will correct itself, but of course, anyone actually hedging with futures isn't speculating on the exchange rate and is exempt from it.
So if bitcoin was a ponzi scheme, or any other combination of adjectives, the utility of bitcoin is not actually diminished, so the argument is moot.
