When Bitcoin will be universally accepted accepted by Government, of course it will be taxed accordingly. Do you think it will still be as in demand as it is right now, that makes its price higher and higher everyday.
Does the bitcoin community is ready for this?
It is impossible to have a tax because it is decentralized , and if that will somehow happen it eill still be in demand, if they its users are still earning profit out of it. If it is still profitable to its users, tax won't be a problem and its demand will continue increasing , same as its price is rising. But I think it would be impossible to be taxed.
