is creating a wall that makes it harder for BTCto be a universal economic currency. Stores may take 1BTC for a product and in the AM that 1BTC could be valued at .08BTC. Obviously theres a ton of positives to this happening I think more than negatives. I for one hope it does though because USD is getting old 
Bitcoin is a universal currency and you really do not need any government to proclaim that,if you look at the user base we would see people from all over the world and that does not make you think that it is universal. Dollar might be getting old and so does the rest of the currencies and it is really difficult to see some currency replacing dollar.Great point. The lack of backing from a country as a currency draws instability fears to the citizens as well. The Dollar is only stable because the US backs it and it is the widely known currency. You could put popcorn in its place, if it was US backed and widely known..than popcorn would be the currency.
Nothing changes,you really need no have any backing from any government ,if people fears about bitcoin ,do not enter it as no one is forcing them to invest in it,for those who like to take some risk and play the game will make a good fortune.
