Mohammad offered Bitcoin-cash exchange services, charging commissions of up to 25%, which is significantly above the current market rate. He met clients in public locations and exchanged currency for them without asking about the origin of those funds.
Common, nobody would pay 25% just for privacy, even if we speak of sums above 1k it was worth the effort to go in another city and deal with a different ATM. And why did he kept meeting clients..
Such high fees wouldn't even be worth it for someone who wanted to avoid taxation.
If you're willing to pay that much you have to be running a large illegal operation involving drugs, stolen property and such.
For me 10% would seem like a suspiciously high fee.
