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?
When government intend to start taxing bitcoin, I don't think that will deter a lot of people from bitcoin, The only set of people that would ,move are those who cannot compromise on anonymity because when you file your returns, you then need to disclose some information as well which invariably, means exposing your identity. Aside that, people who have been working and earning salary didn't stop working because government taxed them. Its a civic responsibility for every citizen to pay tax.
