Not long ago we lived in a world where currency from anywhere other than the nation you were in (or maybe somewhere close by) was impractical to use on a daily basis. Things have changed now and the government's use of money as a tool to keep control of citizens is loosening. For better and worse.
FT Alphaville has a good article about it: "How much does cryptocrime pay?": https://www.ft.com/content/f40b7ac7-bb50-4712-aa7f-5219c2b18... (free sign-up)
To quote:
2025 Chainalysis Crypto Crime Report ... The authors have so far tracked over $40bn of crypto transfers to illicit addresses made in 2024, though they reckon the final total will be north of $51bn.
Some drug dealer is making $20,000/year selling drugs, but the drugs are sold for $50,000 because they had to spend $30,000 on grow lamps and electricity and rent in order to produce them. The same drug dealer also uses the same wallet to sell ordinary lawful gift cards for cryptocurrency and they only make $5000 from that but it's against revenue of $200,000 because the markup on gift cards is small.
For that they're attributing $250,000 of "crypto transfers to illicit addresses" to this person but there was only actually $20,000 of unlawful gain. Overstating the problem to demonize the target.
"The estimated amount of money laundered annually worldwide is between 2% and 5% of global GDP, that is, something between US$ 800 billion and US$ 2 trillion."
