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)
Assuming this guy named "loljosh" was indeed the XC dev, and that of Sync, Cinni, WC, he just admits that to you?
LOL, just LOL. I am Satoshi himself. Screenshot that. I admitted it!
I also have a screenshot of a guy named "asfhlad" claiming he is Satoshi's nephew, do you want that?
The real life identity of the XC was out like decades ago, btw. try something else.
Who is XC dev? atcsecure or loljosh? Are they a team? Apparently atcsecure is paying loljosh for his services:
