All of us hate that part, but traditional methods are being used a lot more in those departments!
For me, this is the problem. When fiat is being used for 99.9% of the instances of money laundering and ransomware, why they are focusing on cryptocurrency? The argument is that cryptocurrency is more suitable for such purposes. But real time data contradicts that assumption. IMO, the agencies are targeting cryptocurrency mostly because it has emerged as a competitor to fiat, and not because it is used in a large way for illegal purposes. No one supports usage of cryptocurrency for illegal purposes. But at the same time we can't allow agencies targeting the cryptocurrency users giving that excuse.
