What will happen on BTC if the government will said that all the bitcoin holder have to pay their tax??
Maybe the expansion of BTC community will get low than usual.
Trade profits are already being taxed. Crypto tax already exist. It's part of a needed regulation that could actually help increase adoption contrary to your statement. You can't expect to make profit and not pay taxes.
When we pay taxes, I just hope that it will never be on the hands of some greedy persons. It is really okay to pay but hey, some reasons are just nonsense. We also want to help one another by engaging on some charitable program.
Governments, also have a lot of budgets so they won't bother.
Are you talking about government taxes or blockchain taxes for holding our coins? If you are talking about government taxes then I am against this because governments do nothing for us and already applied a lot of taxes, while there is no facility given to us. If it is about blockchain wallet tax then it is compulsion of the people to give tax on their holdings.
