Anything can be used for illegal activities.
I think that the main reason why btc has been rejected by society is that there's still much to learn about it and it's easier for them to speak ill of it than to try and deal with it.
I agree with you. Fiat has been you for many illegal activities for over centuries and no one actually wants to reject it. As long as bitcoin keep developing, no one can ban it or even ignore it.
well bitcoin can't spend itself nor have brain neither,it doesn't make sense if government will eventually ban bitcoin due to bitcoin ever being used for illegal activities,if that's really happening then they should also ban those local fiat,its function is the same and ever getting used for criminalities
