A lot of people here saying crypto isn't used for anything illegal... erhm... Remember silk road boys? sure, the feds shut it down (more popped and and got shut down, I don't know personally but there's probably multiple variants on the theme out there now), but nowadays one of the big drivers is getting your wealth out of china (illegally), and are any of these guys reporting their capital gains to the irs? Shit tons of illegal shit happens with cryptos without even going into scams or hacks.
