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?
In a couple of years or when bitcoin hits $10,000. Yes the demand could increase more in the future. I'm not sure about the tax because every country has different tax rules that follows. The government here in my country accepts bitcoin but doesn't recommend using it because they say there's a high risk of getting scammed (which is true if new users aren't informed on different kinds of scamming).
