You did, by using someone else's passport photo....
With this scenario you did fucked up yourself even more. Why not sent your documents in the very first place when they do ask to do such thing? since you would still end up on deciding on giving up your identity.
I do not think this site has the right to ask anything from me(I did not violate anything and have absolutely clean old funds, which is easy to track in blockchain). I owned these bitcoins before they even heard such a word. And now the unknown person is asking me some questions. Why they do not say who they are. They do not give their addresses, their names.
Why does this anonymous site ask for my personal information? They can be criminals (at the time when I own a lot of money).
After reading the part (which I bolded) , I wonder why you still used the site if you consider all of that.
Because I was sure that my transaction can not cause any suspicion.
the current value it is 78k usd and any exchange would definitely ask KYC process the thing here why would use non so popular exchange?
I changed much larger amounts in such exchangers. But only this site has a problem. But in any case I will be more careful since now.
You all say about the fact that I have to go through verification and tell about myself. Why does not anyone suspect this site? Why is this site absolutely anonymous? Nobody knows where they are. How can you just talk about yourself to some unknown people? Yes, yes, I "agreed" with the user agreement but criminals write it too.
