I tried to sell 20k in their Telegram chat and was banned during 1 minute. No exchange listing during several weeks after blockchain start. Payments in console wallet were working from very beginning. Actually, there were working mining pools, including one from developers.
Seems they are not interested in open market. +1 to scam possibility.
Did you just offer to sell some coins in their telegram channel and then they immediately banned you?
Yes. I was in channel for 2-3 weeks, reading and rarely commenting (last my comment was more than a week ago). Posted "WTS 20k if you know a good escrow" or something like that and was immediately banned.
