If the governments banned cryptos,
if they dint now, they never will be. they will just add tax when u converting into real money.
also, tax on every transaction you are doing in your country. in that case u don't have to pay tax when u converting into cash.
they don't care how u make money. they care about tax only
regulation is already there with tax in most of the developed countries. what u do online... clicking all day tabs who cares
