I think the Police worldwide are not really super advance to track the slander. Wallet address can simply be track once the owner is just like us a simple person. But it the owner is knowledgeable in crypto and know deeper than the Police. They cannot track and couldn't give justice to the victim. I hope one day there will have full protection not just for them but also for us who experienced hundreds of scams.
This is the good part for the victims. There is no hurry to catch the scammer immediately when cashing out. The blockchain data are written in stome and the analysis can even be done in years from now. A little mistake in one of 1000 transactions and the house of cards collapse for the scammer.
If someone pulls out a scam such as this one, then we can assume that he won't be stupid enough to leave some link to his identity that can be traced. The Bitcoin wallets that are used for this extortion purpose will remain inactive for many years. And even after that, the coins will be moved using a Bitcoin mixer or will be converted to altcoins or fiat using P2P platforms which doesn't require KYC information. It is still possible to trace the perpetrators, but that is going to take a lot of effort and the law enforcement authorities won't be interested unless some high profile narcotic or terrorist linkage is there.
We have to admit that someone could pull off a scam on the back of crypto, say Monero, but at the same time we should talk about the good things that crypto enables us to have and to do.
