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?
Bitcoin will never become the official currency of any state. No state will ever give up its national money, because it is on national money that the economy of any state keeps and develops. If the state switches to the use of a foreign or "neutral" currency, which cryptocurrency is actually, then this will be very detrimental to the economy of such a state. However, it will not fall apart if it again switches to using its own currency.
Cryptocurrency can have a positive impact on the states economy if it goes along with the national money of the states. This will happen in the future.
