Some coins he has made are: Synccoin, Cinni, Whitecoin, and X11coin.
Those coins have been made by 1 person, loljosh, as the devs themselves(claim to be devs) dont have any understanding of the actual coding, check their history posts as well, they never answer direct questions about anything technical..
I'm sorry for stakeholders/bagholders on those coins, but x11coin is just another coingen coin if you mean, with just advanced features. (coingen is a website that creates alt coins for 0.1 btc, loljosh makes better alt coins for 0.4 btc)
You will be cutting your wrists if you don't sell your DRK now. It's going to go under 1m sat once you all move to X11
