Again, law enforcement agencies (from any country) is strong on the weak and weak on the strong. I look forward to the day (although I don't think it will ever come) when these agencies decide to investigate Deutsche Bank, Credit Suisse and many other banks where money, gold, jewelry and art have been kept for decades. In any case, what is most used for criminal acts continues to be and will continue to be cash, as agencies and governments point out the one thing they can't control, crypto.
