I mean vs. traceable crypto. When you mine crypto, it essentially poofs out of nothing into your hand: there is nothing to trace it "from", as it were, on the blockchain, as the electricity you paid for it isn't recorded in that ledger; so, if you want to do something illegal with money, and you need to figure out a way to control some funds that no one can work out "is you", mining crypto is a great way to do it: you pay for electricity in fiat and obtain a fundamentally unrelated pile of crypto.
