CipherTrace just published their Q2 Cryptocurrency AML Report and found it interesting that Bitcoin still reigns king in dark markets and cybercrime. Most people associate privacy coins even just 4% involve Monero.
Even in the case of malware and ransomware, ETH used in only 1% of instances and BTC used in 98% of cases.

Its the same people doing 'gray area' transactions who are the same ones that are into BITCOIN
They go together hand and hand and its a way to do what you need to do without leaving paper trails
