I have been thinking of this for long and the reason being that a lot of bitcoin transaction is going online everyday in many countries and i think government can generate IGR from this if possible. I am not a programmer and i have a little knowledge about bitcoin technologies but i just want to know if it is possible.
Yes it is possible if government will handle the cryptocurrency in different countries. It was a very bad idea if they will place tax on bitcoins since the tips on exchanger is very expensive today. Placing a tax on bitcoins is a very bad idea for the government it was like they will only milk the miners from getting taxes to them.
i think its a impossible thing, due a lot of bitcoin addresses, and people can make multiple bitcoin addresses i think that was impossible.
did government want to track a whole of bitcoin addresses ? i dont think so, it really need a lot of time
