No one knows the actual founder of ChipMixer.
The wanted person is only a single man and I am really doubtful that he is the founder and the only person who operated CM over years. He is possibly a canary from a whole CM team.
I read through the court documents pretty thoroughly and it appears it was a one-man operation. Funds tied to ChipMixer server payments were traced back to that particular named individual. Its hard to say how much he profited from the service; after all, it was technically free. And he had a separate account on the forum that he used to make trades... from the looks of it he certainly wasn't "wealthy".
Damn this thread. I would still have a lots of BTCs by now if I had not read this thread! My bad decision last year was affected by this thread. Now BTC is too expensive and I can't get enough BTCs as I used to own. I feel so sad each day seeing price of BTC increasing day by day. I would have been a millionaire now if I had not sold most of my portfolio last year when the BTC price was only at 10k - 12k.
