Talking about bitcoin specifically the percentage of illegal activity is even lower, reaching to 0,5% compared to the total volume of transactions.
I see, makes sense for Bitcoin as it is relatively easily traceable unless you use shady on and off ramps (exchanges without any KYC at all). The risk is of course to get scammed when you deposit at such exchanges.
In the end any money will be used to commit crimes, no matter what the type of money is. Digital, cash, pseudonymous or anonymous, it doesn't matter.
Even centralized digital money will eventually be used to commit crimes. There are always ways to play the system and criminals will find those ways.
Exactly, literally everything can be used for criminal action. They tend to fear, but some of them are also jealous because they were sitting on the sidelines seeing how the price exploded. Then the good friends comes around and says "oh my god you what's happening with bitcoin"? And the answer is "yeah it's only money for criminals".
