Stop dealing with illegal shit and you ll not have any need to use crypto mixers.
Only after you stop beating your wife...
Seriously i have as much proof of this as you have people using mixers are doing illegal things.
Wanting some level of privacy is not illegal. I would have expected people using BTC would be better at realising this.
It's called Bitcoinlaundry it's literally laundering money and only for the reason of legality, bitcoin is already anonymous enough for the sake of personal privacy, going through mixers for normal transactions isn't normal. You're a fool and living in the clouds if you think the mixers are just for people who want to be private for private sake, it's for drugs or stolen coins just like usd laundering.
