He has a contract with an exchange that includes privacy and he can not give me information. No screenshots, no contracts, no transfers, but I saw that he has 20 bitcoins in his user.
I have a strange feeling that it is a different kind of contract -
50/50 and we don't know each other.
Lesson - if you want to invest a serious amount, it is better to spend some time and learn about things you want to do. You do not buy car without research, you do not buy house without research, but you buy bitcoins worth house+car. Why you did not use the exchange yourself? Why "dark net", not the normal one? For 1k? 1k from 40k is 2.5%. 2.5% is very often daily change of bitcoin...
Ah, and you know - there is also POLICE, but I guess you do not have any contract with your friend, you just send him your money.
