We had this discussion in Czech Bitcoin community about getting operators of darkmarkets.
What do you know about this?
How do fbi or other government agencies get these people?
We talked about
1) Bitcoin is pseudoanonymous and some companies business is to trace transactions
2) They can get to place where they host this darkmarket and find IPs or some data that can lead to find the admins
3) There was this guy who sent some profits to KYC exchange on his mothers account
4) They have to use node for transactions so they can maybe traced by IP of node (but what if it is through TOR)
But what if they used only Monero and Zcash (or other privacy coins) or they use some mixer?
Are there other ways to get to them?
If I was wrong in something, please tell me.
