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?
Maybe bitcoin cannot be an official currency of a certain country because each country still have to have its own currency that represents in a way its state and progress. But bitcoin can be part of a country's progress. It would not ruin a country unless people widely use it for illegal purposes. It depends on how it is used by the people.
