It would have been good if we can see a comparison between the amount of crypto used for illicit activities versus the amount of fiat used for the same purpose. I guess the amount for cryptocurrencies would be smaller if compared to the amount of USD used in illicit activities and not to talk of other fiat or countries.
A few years ago (I can't remember exactly), a good friend of ours from another forum (Leo) wrote somewhere that even less than 1% of all illegal transactions were in cryptocurrencies, and it seems to me that this percentage is still very small (definitely less than 5%). When we think about it, it can't be different considering that the number of people who are in some way involved in cryptocurrencies is less than 5% (globally), and most of them use cryptocurrencies exclusively as an investment, not as a currency.
The reasons for the decrease could be because some bad actors which used crypto for illicit activities are getting known and revealed. Cryptocurrencies is not as anonymous as people thought it is, therefore having fiat as their preferences. Or because the bull run is not yet significant enough.
Except perhaps the so-called
"private coins", everything else is very easy to follow, and those who thought differently when they did bad things with their cryptocurrencies were often unpleasantly surprised.
