Very related. Most people believe that since bitcoin's transaction hash is open for every one to read, it is not possible to be used for crime. I choose to differ from that. Bitcoin's user anonymity makes it very possible to be used for crime. Let's take a look at the number of scams happening around. Once a Bitcoin has been transferred, users can only read the transaction but it is nearly impossible to use that transaction to know who the recipient is. This is why most blockchain require their users to register with their full name and pass KYC. It makes it possible to track transaction and know the exact person behind a transaction in case of fraud.
I don't want to conclude in a negative way but since the digital assets born and so the scammers being born too and so far the main crime that I think is correlated with bitcoin I might say in a direct way is scamming and fraud but other crime that being connected with the platform is indirectly correlated however some people choose to blame it on the platform. I think fiat is still the most common currency related to crime committed. And yeah it's a big help that every blockchain requires a KYC for the proper verification of the applicant.
