Telegram channels can pump a coin by 50%-200%...

I ran into couple of this channels on Telegram (it's an encrypted messaging software like whatsapp)
I joined a couple of them after a friend advised me and said there are channel who are giving signals on specific coins, and making them jump by hundreds of percentage in a few minutes,
how is this possible? If it's that easy to make profits on those altcoins why doesn't everybody doing it?
Just as an exemple, one of them is t.me/whaletank and http://affiliateceo.blogspot.com/ , most promising so far.
Can someone recommend me on few others to check out? I don't even know where i can search for more of this kind of groups, but I'm sure there are more..
I would like to join any kind of a large group with 1000+ people on it, I find it the best way to make profits right now when the whole market just keep crashing.

Yes it is definitely possible, They simply tell all of their member to buy a specific coin and that's how it gains lots of % very quickly.
On some of this low population channel i would say they are most likely coping others, and are complete sht, cause u enter the trade too late after everyone already sold..
But the one you gave seems legit, with a very high population, and they seem to give more then just signals, so i would say it definitely worth joining.
