I didn't even believe if that was a hacker, i do believe if that was inside job. Only dumb people who still called that as a hacking incident.

tether already frozen USDT related with what people called that as hacker. The hacker was converting all of centralized tokens to the decentralized token that can't be blocked like USDT. I think that you shall check the latest news again. It's clear hacker was avoiding the centralized coins caused by he worries his money got blocked.

it's not weird at all since none can block your coin in ethereum blockchain.
