What would happen if dollar would lost huge value and the the US Government gives a proof of ownership of Satoshi mined bitcoins?
Maybe this was asked sometime before I applogize for repeating the same question.
In other words what if Bitcoin iwas created by the Government?
no you are the first one who came up with this conspiracy theory. congratulations, your big tinfoil hat does work. you should start making more of those and selling them for profit.

in any case the government is never going to create a decentralized currency which is taking the power from them even if they control a large amount of it. and not to mention if they really created bitcoin then they would have never stopped mining it. that doesn't make sense to create it, mine it for a while then go away and let it grow as a decentralized currency and create lots of altcoins some of which are focusing on decentralization and anonymity even!
