As for a newbie like you, I suggest to never join or pay any of them just to join a pump and dump group. Don't be deceive by their fake sceenshots of their portfolios because it can be easily edited.
I agree with him, that's just bullshit.
Pumps are just dreams, like lottery.
If you still don't believe: Invest very less on that pump coin, so it doesn't matter how much the coin goes down before you are able to sell.
I also made some experience with pumps, but not good ones, so simply just don't so that!
