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?
This is really a problem for the central banks of any country . And all the countries are concerned about that fact . This is why chi a gov might (!!??) have banned ICOs. But some country like Japan, Australia ligalized the bitcoin, that means the have applied some method to bring crypto currencies in the tax system ,all country should follow them not china.
