the bitcoins of my friend’s girlfriend were stolen
How can they prove this? The girl could have sent it by herself.
I had paid cash to somebody and in turn received 0.09 bitcoin to my wallet I found out through “blockchain.com” that the bitcoins (of my friend’s girlfriend) were stolen/withdrawn to the same wallet from which I had received 0.09 bitcoin.
What are the odds of you by coincidence buying coins from a complete stranger, who also happens to have just robbed your friend?
the testimony of the manager of the exchange site which is that I had informed the thief to deposit the 2 bitcoins in the exchange so that I could convert it to cash
If I deposit Bitcoin to an exchange, I don't call the manager to tell him why I'm making that deposit. What exchange is this, and why would a customer inform the manager before making a deposit?
