Fact is:

- chipmixer lied in it's claims to delete private keys.
I don't know how can anyone defend them after it was made clear by users. I suspect it's about the signature campaign, at the end ukhm.. corruption or stockholm syndrome?

Therefore it is justified to assume that chip mixer ran from very beginning as private honeypot for the owner and gathered all kinds of information.

Based on what kind of actors moved money through chipmixer, i don't think the guy will be ever found alive.
Other people might be looking for him to find out what the truth was. Not only law enforcement.

He not only f*** himself but also other people.
