He's an idiot. Crypto was pitched early as an anonymous way to spend money and people have been allowed to go wild with it with little regulation for some time.

Unfortunately that has given the impression that it is truly anonymous. The reality is that block chain technology gives people the ability to track spend in a way you can't with any other currency. It's easier to track the path of a Bitcoin across any transaction anywhere than it is to track a usd within a single financial institution. The Bitcoin has a unique ID that is recorded at each transaction and embeds information about path dependency. By design, you can see every single digital wallet it's passed through in order. If your wallet is anonymous, they wouldn't be able to tie it to you, however it's the single point of failure. How do you fund it, spend it, or cash out without identifying yourself?
