can be recover by Bitcoin address? no there is no chance mate.
or maybe there is also Inside job? who knows right?

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.

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.

Sometimes these sexual extortionists don’t have anything about you, it’s just threats. That’s why you shouldn’t be replying any email that you know nothing about. If an email is coming an unknown sender it’s very best that you don’t reply such mails. And this is another reason why we should mind the kind life we live and avoid sending out images that we shouldn’t.

But like I said, when you get such mails from these sexual extortionists, it’s best not to reply , you can report to the police station and a lawyer. Like I said, most of these extortionists don’t have anything on you, they are just threatening you, and if you engage them, it gets worse.

But if you use a coin switching service that doesn't require KYC and you switch into Monero and from the provided address send it to another Monero address, it's over. There is no single way in the world to trace down transactions on the Monero blockchain, at least not from what we know to date.

If the criminal goes through Binance it might be easier, but still there will TOR and or VPN involved. You just can't stop these coin switching services because they can be founded anywhere in the world. If you can't shut the website down, how are you going to stop it? Surely the risk is with the attacker that the person running the switching service steals the funds, but the attacker just goes step by step, doesn't send 4000 BTC. If they do it right, no way you catch them. That's why it's more effective to force people to prove where the money comes from if they ever cash out. I am not saying that is the solution to the problem, I am just saying that KYC won't stop (s)extortion at all.

A couple of things regarding dothebeats post.

In this age when every customer is video'd at every Walmart checkout and police simply park a car with license plate reader and video at an exit to film drivers after they've removed their facemasks, anonymity today isn't expected.  It's the world we live in today.

And with bitcoin thieves having stolen over 11.8 btc from me, I don't want crypto currency anonymity.

Sextortion: I had a compromised password.  No cellphone nor camera have been in my bedroom.  I got a one of those sextortion demands.  I ignored it.  They target those with a compromised password not those they've hacked.

The US shutdown BTC-e in Bulgaria because they refused to comply with proof of identity FINCEN requirements and bitcoin laundering.  Vinnik was arrested in Greece by the Greeks with US authorities but held that his Russian Orthodox faith was essentially the same as Greek Orthodox and so shouldn't be held in US jails.  Don't know why, the Russian Orthodox church has a huge estate on Long Island Sound near where I lived and a church in a town a little ways away.  So, the Greeks sent him to France where he is awaiting trial.  

I went off the subject a bit but what I started to ask is why doesn't FINCEN play wack-a-mole with every exchange accepting bitcoin ransoms or extortions if they can't provide individual identification of the perps.  Or is it a case that Russia won't comply with FINCEN requirements?  What's the answer?  Maybe break up the internet the way the EU is banning flights to Russia and Belarus while they support Alexander Lukashenko?  Heck many of my missing ~11.8 btc might be in Russia if reports Vinnik had a boss there who may now have much of the MtGox stolen btc as well as btc stolen from other exchanges over the years are true.

No. While you're right that highly sophisticated transaction and mixing protocols like Monero or (Coinjoin..)mixers cannot be traced directly it can be done in the most cases indirectly. Successful scammers have to manage earlier or later a high number of addresses. E.g. if someone is doing 500 transactions and is only once or twice co-spending the wrong coins (e.g. unmixed with mixed or monero-forth-back-exchanged coins) then the house of cards collapses often.

I was able to link for this reason more than 20% of a Wasabi mixing transaction outputs to their inputs. If you think 20% is not so much then this was the success rate per single transaction. If people are doing hundreds of transactions then only a low % of scammers are able to stay untraceable over time. The scammer ripping off 307 BTC from Exmo exchange in December moved the coins for obfuscation reasons more than 300 times before he did a mistake by co-spending it with other coins. All the 300 transactions were finally a waste of time and fees.

The scammers human brain thinks two or three steps deep but the analytics software goes much deeper. E.g. scammers which move the coins in long transaction chains use manually chosen transaction amounts. They have other patterns then natural transaction chains where A is trading with B and B is buying something for crypto from C.

Remember that Most of the chance wallet owner are anonymous until time comes of they need to withdraw .  meaning the funds may sit on the wallets for those long time and just wait for a chance to segregate the funds little by little.

I see what you are saying and I know that companies like Chainalysis can go far beyond what many people think. But if you get your money into Monero and you send it a few steps ahead, maybe just divide it into a couple smaller transactions onto various Monero addresses, how are you going to identify the scammer? Isn't then the only way to crack Monero itself? I see why Bitcoin is relatively easy to trace even when mixers are used, but for as long as you are careful with hiding your IP and you are not unlucky using an infected TOR node, there is no way to really find you before any exit. Am I wrong?
