I am not.
Not being funny or trying to send a message here. But just imagine.
There are only 20 or so.. casascius 1000 btc in the world.
Imagine someone trolling those coins sending insignificant value to them. The damage to the original value would be enormous.
My point is that I disagree that anybody can donate to a public adress without the owner consent.
are the coin's addresses publicly known? Not exactly rocket science https://bitinfocharts.com/top-100-richest-bitcoin-addresses-14.htmlDamn there are many millionaires out there... Around 20 1000 BTC coins, some of them already claimed, and around 400 addresses with exactly 1000 Bitcoins. Maybe the number could be lowered by the time when the transactions have been made, but would be too much trouble just for the lulz, and I think at least some dozen of possible addresses would still need further investigation. |

Different stuff that can't be compared exactly. Gold for example can be used for electronics and arts, but use Bitcoin for any out of inside the computer would be impossible, and Gold is something that would not go away with a couple of EMP in some strategic locations. Also not everyone is (or should be obligated to be) in the internet in order to have savings and do transactions(like some kind of mark of the beast).
There is a quote from Satoshi about gold:
"As a thought experiment, imagine there was a base metal as scarce as gold but with the following properties:
– boring grey in colour
– not a good conductor of electricity
– not particularly strong, but not ductile or easily malleable either
and one special, magical property:
– not useful for any practical or ornamental purpose
If it somehow acquired any value at all for whatever reason, then anyone wanting to transfer wealth over a long distance could buy some, transmit it, and have the recipient sell it. Maybe it could get an initial value circularly as you’ve suggested, by people foreseeing its potential usefulness for exchange. (I would definitely want some) Maybe collectors, any random reason could spark it."

Eu ainda prefiso usar ADVCash! Uma taxa fixa de $2.99 + 2.99% de qualquer operação não EUR/USD. Se for EUR/USD, só paga uma taxa de $1.99! Para quem for trabalhar com limites intermediários, agora se forem com quantias maiores é necessário colocar na ponta do lápis a viabilidade, e VIVA O DÓLAR! HAHA Agradeço ao Temer.
$2.99 + 2.99% ? Por transação? só os $2.99 já são mais do que os 5 reais de mensalidade, e quase o preço do cartão, se for comprar um nas lojas. você realmente gosta de pagar mais tarifas do que seria necessário  mesmo se trabalhar com dólar, a taxa fixa de $1.99 só compensa para transações de valores relativamente altas, para valores menores deve ter opções melhores, mas ainda sim quase certamente é melhor do que pagar IOF |

Buy some silver wallet or any other buyer funded coin if you plan to save your bitcoins in a physical coins. You never know the result
Don't let others know the address associated with your coin if you fear someone may troll you by sending other transactions.
And again, don't do it.

Look for the source of whatever study they quote as "source"
It is not uncommon that the study will say the opposite, and they trust that everyone will be too lazy to check the source and will accept the lie.
In fact they didn't provided a link to the study neither a proper citation, making things harder.

Over the past year and a half Bitcoin has been on a spectacular run, rising in value 140% in 2016 and now an additional 49% in just the past month. This surge in value has invigorated Bitcoin backers convinced this boost in value makes Bitcoin a more credible currency, that it is a sign of the cryptocurrency’s strength. Yet the wild swings, both up and down, in the value of Bitcoin do not make it a more plausible substitute currency; they make it a speculative asset, a get-rich-quick scheme. Is Bitcoin the currency of the future? No. There are two big problems with bitcoin as a currency: its value is unstable and its transaction processing is too slow. The most important feature of a currency is that it be a stable store of value. This credo, ably explained by Steve Forbes here (among many places), is vital for a developing country economy to attract the investment it needs. Even in developed countries, as John Tamny explained here on Forbes.com, a stable currency value is the key to investment because those who invest are expecting a stream of future earnings to earn back their investment plus some profit. Instability in currency values mean that an investor cannot accurately predict the value of those future earnings. This uncertainty makes investments less valuable; thus, less investment happens. https://www.forbes.com/sites/jeffreydorfman/2017/05/17/bitcoin-is-an-asset-not-a-currency/#c3c0b392e5bc |

...além de também utilizar Monero. Um novo ciberataque em grande escala para roubar moeda virtual afetava nesta quarta-feira (17) centenas de milhares de computadores em todo o mundo, de acordo com especialistas em segurança cibernética. (...) O novo malware se instala em equipamentos acessíveis através da mesma vulnerabilidade do Windows utilizada pelo WannaCry, uma falha já detectada pela NSA, que vazou na internet em abril. Depois, cria uma moeda virtual não localizável chamada Monero, comparável ao bitcoin, rouba os dados dos usuários e recebe o pagamento em moeda virtualm usando endereços criptografados, sem que o usuário perceba. (...) O grupo Shadow Brokers disse em comunicado online que, a partir de junho, vai começar a liberar software para qualquer um disposto a pagar pelo acesso a alguns dos maiores segredos comerciais do mundo tecnológico. Em um blog, disse que está criando um "despejo mensal de dados" e que pode oferecer ferramentas para invadir navegadores de internet, roteadores, celulares, além de artimanhas mais recentes para Windows 10 e dados roubados de bancos centrais. Além disso, está pronto para vender acesso a vulnerabilidades não divulgadas anteriormente, conhecidas como dias-zero, que podem ser usadas para atacar o mais recente sistema de software da Microsoft Corp, o Windows 10. A publicação não identificou outros produtos pelo nome. O Shadow Brokers também ameaçou despejar dados de bancos que usam a rede de transferência internacional de dinheiro SWIFT e dos programas nuclear e de míssil da Rússia, China, Irã ou Coreia do Norte, sem fornecer mais detalhes. "Mais detalhes em junho", prometeu o grupo.

Miners can mine blocks and confirm transactions using any criteria, and nodes can only see transactions, by themselves.
With no confirmations there would be no network, so the miners have the power of choice

What would be counterfeit a bitcoin? Bitcoin is no physical good that could be counterfeit I think the question has no real meaning. Maybe you wanted to say something else? |

Agora vai acabar a farra de vender um real.
Hi William,
We have an important announcement about your Xapo account that will affect you - so please read!
In the next couple of days, all Xapo users will begin to pay the miners fee themselves in order to send transactions out of Xapo.
Taxa chegando a 420 Satoshi/byte e sem sinal de diminuir, uma hora isso teria que parar, ou o custo poderia ser grande demais |

Você tem certeza que esse PDF tem alguma coisa a ver com Bitcoin?
E o que acabou foi a consulta pública, a decisão não foi feita, e nem sei qual seria o prazo

It's a lot, do you think it will go up more?
there is only one thing that is making me nervous to be honest. and that is the ETF news, we all know it is useless news and it is not going to change anything for bitcoin but i am afraid the whales may take advantage of it's possible rejection and dump. apart from that $1800 is not a lot, it is very cheap considering bitcoin potential. so it will surely go up even if it means going up in long term and dipping in short. since it seems that there is no deadline for an appeal decision, I think we won't hear any news for a long time, considering the first ETF decision took 3 years to be made. Also $1800 is there and a certain triangle has been broken upwards, so the perspectives for the future are good, if we keep this price for a little longer |

Another spam attack. The mempool jumped from normal levels to 150k unconfirmed transactions in less than 24 hours
I don't know what are THEY trying to accomplish with this, surely is costy and can't be maintaned forever.

Essas tarifas internacionais que pesam no bolso do cidadão: Tarifa de uso internacional – Mark Up 5,00% IOF sobre transação internacional – Imposto Nacional 6,38%  Esse cartão não tem foco internacional, pra isso existe os AdvCash da vida. Alguém já usou este cartão ? Estou pensando em dar uma chance porque é uma idéia para fazer uso rapidamente de um valor que esteja em bitcoin numa compra por exemplo. Há algum limite de valor nele de movimentação diária ou isto é simplesmente limitado mesmo pelo saldo depositado no mesmo ? Tem na matéria os limites, mas tem que confirmar no site porque eles podem estar errados ou desatualizados. Eu já tinha visto na Bitcointoyou, mas como a taxa de carga era a mesma de uma retirada em reais, valia mais a pena simplesmente retirar pra uma conta e usar o cartão de débito. Se a taxa de carga for realmente 0 para Bitcoin então vale a pena utilizar se o gasto mensal for mais do que uns 200 reais, dependendo de como eles calcularem a taxa de conversão. A propósito, como a taxa de conversão é calculada |

A "playing wallet" da directbet.com paga as taxas de mineração e a quantidade mínima para retirada é de 0.001 BTC. O mercado bitcoin sempre pagou as taxas de retirada, a partir de 0.009 BTC, embora aparentemente eles vão deixar de bancar o custo de retirada "em breve".
E provavelmente tem mais opções.

Bitcoin already doubled this year, before the half of the year, why not double at least once again?
In 2013 Bitcoin has between the first "small" rise to $200 and the second one up to $1000+ by the end of the year, maybe history will repeat itself, in a more sustainable way.

You guys really need to start pointing out to a flawed metric that is easily manipulated to point out how BTC is collapsing
You just did. Any readers should understand that I meant to say to stop, but even to start still applies. We need to start pointing out at the fact that BTC dominance thing on coinmarketcap is freaking stupid. Most noobs seem to look at that and think "wow, BTC is done for! better buy some alt". Those are all the idiots buying scamcoins thinking they are on board with the next bitcoin. They will learn the hard way. one Bitcoin vs hundreds of other alts. even without taking into the consideration if the numbers are accurate or not, one being as big as hundread others shows some kind of big dominance, in my opinion |

All publicity has something of good. People see confusing news, then some of them will look for themselves for more trustworthy sources of information, some of them may end up here, or any another place they can find more accurate information, and end up investing in Bitcoin.
At this point even if a very few % of people that hear the news go deeper and buy Bitcoins, the effect in the economy wouldn't be insignificant
