Two questions.
1) How exactly can a hacker escape with a mixer?
2) Why do mixers exist?
1- By sending their dirty coins to a mixer and get back clean coins.
2- To clean your dirty coins.
What do you mean to clean them? What does the mixer exactly do? Does it send your funds to thousands addresses? How is that clean?
They give you somebody else's coins instead. They do this with thousands of addresses in the end you won't be able to track down where your coins came from.
I don't really know how their algorithm works. If I did, I would create my own.
