Hiding wealth

Owning Bitcoin is a way to hide your wealth. Maybe this will be a thing in the future, seeing how there is a trend for hate on the rich people in the world?

Is this a crime of sort, hiding your wealth? I am not talking about tax avoidance. I mean, if you hide your wealth because one thinks it is shameful to be a rich person.

What if countries set a limit to the maximum wealth of the individual? Would that even work? Moral compass?

I have so many thoughts...
