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?
We have different governments and if you are just talking about the USA then it will be a hard fight and I doubt they will accept it. It is like surrendering their loved US dollar with another currency.
That won't happen to them. They would rather create another coin than accept what bitcoin is specially right now where it is so valuable.
