I don't know about him but I had an awful luck with ZCL, being BTCP my idea, given to Rhett at Slack in September/October (which he said the idea is "not needed at all"). I was 100% in ZCL from April-June 2017 to November 2017 and no one can imagine how hard I tried to convince Rhett (and other developers) for further development at Slack, Twitter, Discord. Even if you search the old posts of this thread, you'll see how hard I tried to gather community fund for Rhett for further development, but nothing worked at all, thanks to Rhett. Literally, my whole 2017 spent on promoting ZCL everywhere and I ended up with a loss. I was afraid to hold more as ZCL volume at Bittrex was getting less than 2 bitcoins per day (afraid of getting ZCL de-listed from there).

Trade history still available at Bittrex.
