If governments make BTC transaction, withdraws and deposits illegal, BTC will almost end, only some people will pay and receive BTC for most illegal practices
Would you risk to be arrested having BTC?
Most of the people won't
We have to be realistic, it's a utopia think that people will keep using BTC risking to be arrested
I think this is the scenario that happened in India, because people fought for crypto, the government lift the ban and I think it happened this year.
So eventually the government will be fair and people will win, unless you are living in a country where there is a dictatorship.
