Total numbers right now, it's like it's over $100 million stolen? It's like 1600, 1800 Bitcoin.

Thousands and thousands of addresses, probably thousands of victims. Uniquely like these are all super hardcore Bitcoiners, who believe in self-custody and cold storage and hardware wallets and safety and that makes it painful.

It's basically, like, six days ago, seven days ago now. Um, it's been a free for all since. Because there's basically five years of seeds and private keys that that the various attackers are basically mining.
