I'm struggling to understand your connection at all. There's a difference between legality and ethics. Something can be illegal and it would be immoral for someone to obey that law. Similarly something can be illegal and it wouldn't be immoral for someone to ignore that law.

The point is just bc someone happened to benefit from it doesn’t make it good overall. Im sure some people must make money off various mlm schemes

and who exactly is harmed when two people engage in free trade with resources they own? In your example the bank robber does not own the money, it was stolen and the robber has no claim, only possession.

Easy - in case of btc money is stolen from people who subsidize cheap electricity (ie taxpayers). Various altcoins - future holders of bag

you're using electricity just to comment on this thread - presumably you're okay with that, so what makes your electricity usage justified and not bitcoin owners? Both forms of electricity have been paid for (presumably) with resources you own and traded in good faith. It's not illegal to use electricity to mine crypto in the vast majority of places.

as for altcoins I really don't know what your point is
