Hmm maybe its legal since I actually see some dump and dump group but I don't really know if they are successful for that doing, But also as you can see if their are more buy orders it can set the price to go up and dump if rampant sale will occur so I think some rich people do manipulation act to earn and I don't see anyone sue for that actions so I conclude that kind of act is legal since it hasn't disobeyed any law of certain ones.
Yes it's legal, why shouldn't it be. But I totally agree with you I don't think the little pump'n'dump groups aren't really successful. It's like a ponzi scheme. The ones starting (mainly the one announcing the coin or leading the group) make the most profit and only try to find followers an people to whom they can sell. It's only about taking the money from the dumb ones.
