It's not Illegal, as any Cryptocoin exchanges aren't regulated. But in joining one, you probably have a better chance of losing alot of money than gaining, since the guys at the top always make sure they get out first, then they give the signal and everyone else scrambles to make it out alive.
I't's not illegal definitely and I agree with you that the one that created this group are just using people to make a huge profit,they dump while you pump, they accumulate early then dump when they announce that they are pumping so it's usually the other way around,it's like go buy my bags of shits.
Exactly, unfortunately people see past it or they decide to use it anywhere in an attempt to make some gains.
But when you look at the last pump-stats of the channel, there is no pre dump in the charts, strange
