I have just got a mail from someone called Mike Demarinis blackmailing me to ask me to send him money. I know it's a joke, because i have got various passwords for different things. The guy simply don't know me.

But is there anyway that i can track the guy, like IP or location and call the police?

I want to find out where this address is from: bc1qz5ufptmvfkm4cjegwrfhqypvzum56phznm5raf

The mail is pretty nasty and frighteningenter image description here

No, there's no way for an individual to tie an arbitrary address to a specific person. However, it is sometimes possible for companies or governments to do so if the person went through a KYC/AML or identity verification flow on a centralized exchange site (i.e. Coinbase).

This is how the IRS was able to track people with large returns down for tax purposes (https://tokentax.co/blog/does-coinbase-report-to-the-irs/).

All bitcoin transactions are entirely public, just pseudonymous. So, if a company is able to tie an individual to any address, they can easily track where that address sent coins and go from there. So while you might not have any course of action yourself, it could still be worth reporting any information you do have to authorities.
