I came across some site which is like a bitcoin washing site but peer to peer, the site itself acts like an escrow and allows people to trade apparently 'dirty' bitcoins(maybe from hacked wallets im thinking or stolen, scammed etc) for 'clean' bitcoins. Now i don't know if it's legit the whole idea of it. I always thought bitcoins were anonymous either way why would someone even do that and lose 30 coins?

Although I'm quite new to this stuff so if anyone knows more about this stuff I'd be happy to hear your opinions/experiences on this.
