The lead Dev just left Max's chat group. Max and his group has nothing to do with CHC except they bought it like they have bought other coins like PING and LINDA.
The last post of the Dev was that he was getting back to working on CHC and he hopes the real community stays by this coin since the pump and dumpers have moved on since they are on their new coin Linda so you just may need to post in that thread.
Who is the real community? From what I see this coin was at < 15 sats and basically no volume for 2 years.
CHC wallet is under maintenance on Cryptopia. I don't know how long or why, but perhaps someone has contacted their support? It's just the start of the work day in New Zealand right now so hopefully that means they are working on it now.
I reached out to them, haven't heard anything since.... good time to buy too....
