I do believe that, but I suggested doing things transparently if it suits you most.
It depends on many things (the country you live in, your age, your financial goals and current situation), but you can just declare the bitcoin you own and the bitcoin you earn and you 'll gain your missing peace of mind.
Again, I never suggested and never will suggest to avoid taxes or break the law.
I pay taxes because of peace of mind. I think OP is talking about 2 different things: good privacy, and being able to spend 6 figures. Those two aren't compatible, you can only have one of the two (legally).
