I dont need your advice how dangerous those channels or groups are i know myself just Im looking For good pmpp channels.
If you dont need anybody to tell you how dangerous this pump signals are because you already know, then there is absolutely no need asking here, you should just head over to telegram and search for "crypto signals" or "crypto Pump groups", i believe you will get over a million results, the only problem would be " which to choose and which to leave, cus they are to many of them".
But let me tell you something, 99 percent of this groups are scam, better learn how to trade on your own and dont depend on signal groups, you might be lucky enough to make some money for a while, but when the bad luck hits you, you will loose everything and not have a single penny to show for your years of hardwork following signal groups.
Yes they maybe buy b4 then give out signal i don't Care about that i'll make quick in quick out its still worth more then waiting like fool when btc start doing something Im here to make a lot money as possible with crypto dont really want to waste my days waiting for btc start doing something.
Many of those who waited are all millionaires today, you that have been doing quick in, quick out, how much have you made so far ?
Beside, there are several other good altcoins to invest/DCA in if you feel bitcoin is too slow in doing something (as you put it), or better still, learn to trade and stop depending on pump and dump as a way to make money.
