It's a service providing gathered crypto signals from different premium groups / arbitrage trading / volume changes in different coins / crypto advices / news / icos and more.
It ain't a new crypto service since there are also others who already offered crypto signals/arbitrage trading and volume exchanges in different coins for free but only for a limited time like what the channel you promote is doing. For now since it is free, I might consider taking a peek at your discord channel and see for myself if it brings good crypto signals or not.
