Also keep in mind that exchanges don't play nice to mixers - Don't send mixed BTC to exchanges e.g. Binance or they might give you trouble over it.
Hello everyone, I need help to clean some bitcoins. Does anyone know about some bitcoin mixer?
What do you mean to clean some bitcoins. There are no clean or dirty bitcoin. You need to break the trace that's the better term for it. Check around the forum, you will find many mixers are there. So far I can remember: Yo!Mix, Sinbad, Coinomize, MixTum. I am yet to check MixTum. Already used the rest of it but I personally prefer Sinbad.
When you are mixing it's better to use more than one mixer. Send coins to mixer one then send the mixed coins to another mixer before bring them back to the permanent wallet.
What is more ironical about "clean" bitcoins, is that some exchanges consideer bitcoins "tainted" after a recent mix process.
You can just make a few hops (transactions) to other addresses you have, to make that mixing undetected by exchanges.
