Many members reading this thread would welcome it if you are willing to report Tillkoeln (the owner of Unnamed Exchange) to the police. You should not worry about having all the information at your disposal, why not report him to the police with the information you do have and allow them to investigate the parts that you are having trouble with?
So I'm planning to report Tillkoeln to the police to get my money back. I have the proof that he was the owner of Unnamed Exchange and I have the proof about his real identity. I naturally also have proof of sending crypto from Coinbase to my wallet addresses on Unnamed Exchange. The only thing I don't know is how I can prove that those wallet addresses belonged to Unnamed Exchange?
