Well, i just thought, if bitcoin become a currency of one Country, maybe it can destroy that country? Think of it, Bitcoins do not have a tax, and tax are used by the government to make that country a good one, without tax, what will be used to spend and make that country a good one?
What do you think?
of course not because bitcoin is a currency and if it becomes the currency of a country that is taxed instead of bitcoin but its use, for example to buy and sell, and of course what is taxed is the trade tax from buying and selling, most likely the country will be greatly profitable because bitcoin global in nature and not affected by one of the countries becoming more stable than the conventional currency which is always haunted by sentiments between major countries.
If government keeps a track of it as it has transparent system of knowing form where to where the movement of transaction taken place could be traced this will help minimize if any such activities happening which should not be happen. Though it cannot be said 100% safe and nothing wrong can happen but this is the case with even fiat where black money still exists in the world.
