So how can these criminals scam someone out of crypto and then they have the crypto, but can't the police then somehow find those crypto assets?

Well, not all cryptos are traceable.

That's the good start.

For example, there's the currency Monero, which is not traceable.

But if you're a European citizen, American citizen, or Canadian, if you're anywhere in the first world, there's no exchange that lets you sell your crypto if it's Monero.

There's no bank in any Western country that will allow you to deposit money that comes from Monero.

So these people might have to go into the third world or might have to find alternative ways to get KYC.

scammers can get the answer?
