I agree in all probability there was no hack and the attractive Dogecoin price at the time twisted his mind with greed, that is almost a certainty but you are a newbie yet you seem to know a lot about unnamed.exchange and scammer TillKoeln. How?
TillKoeln is obviously a known scammer. Now he thinks everyone is betmaster for exposing TillKoeln's scam ass. Karma is a bitch when it comes for a thief like TillKoeln. That day will come.
He obviously didn't make anything whole because he stole money from people and make it look like he is paying some so he can keep the scam going. There was no hack, TillKoeln just took everyone's money when doge was high. Plain and simple. The hacking excuse is very convenient.
Don't be surprise when the next headline is TillKoeln in a German prison.
