Lots of former poker players in the crypto space. I wonder if I would recognise you 2+2 user name. Mine was DanThePro, a knockoff of a great youtube pro poker player JoeThePro... but alas, I spent too much time watching youtube videos and lurking in bbv4l and the poker profession never really took off.

I think bittrex delisted a lot of their lower volume coins when they started adding in more usdt trading pairs. It may not have had anything to do with gambling.
