I remember this trending on Twitter a few days ago. Some people don't believe it while others claim that even if it is just a small amount, it still needs intensive scrutiny. Most of them miss the point that fiat or other means are still popular though. I don't think this is surprising for people who are familiar with crypto since most of them don't offer anonymity, to begin with, not to mention liquidating them to fiat will definitely need interaction with a KYC platform or something similar. At the very least, this should be a good argument against anyone who believes crypto is this devilish tool that will definitely get abused (or designed for) criminal activity like this.
