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.
It really depends in each country, if a certain country will put up bitcoin in their market then it is not possible to have to imposed tax on it, just like what South korea wanted to do with those people investing not only in bitcoin but to the whole cryptocurrencies as they don't like someone avoiding tax, they don't really want to ban crypto they just wanted to imposed tax on it by stating the real name of each person investing in the market as much as possible.
