While TRTG is a small coin, in my experience it is not a scam.
Trades are active on TradeCX.io (hope that's allowed, meant informationally)
FCB appears to have to make manual chnages and transfers, making them... Kinda slow.
There is movement on TRTG, as far as the github, and they have been applying patches, etc to the code.
Trades fine, on tradeCX,  I stopped using FCB, for various reasons.

It's a fun coin, run mainly  by the community.
And it's just starting.
Check the discord.
