If I had $470 million in stolen crypto, I would target to keep around 10% of that, and with the other 90%, just send them to random crypto wallets around the world. I would do that for years and years and lead the cops on expensive wild goose chases and get hundreds of thousands of people entangled, and then transfer some to me every now and then through different identities.
I don't see how this can be stopped, unless somehow they traced the execution of crypto transactions to a particular IP address and time.
