the only way they can do is to watch the wallet address what if the hacker use mixer before selling it to exchange ? Are they still able to kNow that details if hackers already use it?
This is extremely difficult for the Eterbase team. It's already gone, it will only be back if the hacker will decide to give it back, lol (extremely impossible).
Using such a mixer for this hack is kinda impossible, it's really huge amount of Bitcoin, I also don't know what the hacker will do. The address for sure used in the hack is already flagged in some exchanges or other services.
