If you want to know specifically which coins will be pumped or dumped, you must join the group and of course there will be a fee to pay I'm not recommend that way because you need a big capital also a chance for you to get scammed are high.
Most people paying for those group's "information" end up losing money because all that's happening is the groups recommending people to buy the coins they already own (i.e. create liquidity to sell into).
People just need to stop forcing themselves into a trade. If you don't know what coin's chart offers interesting and potentially profitable trading oppotunities, then you shouldn't be trading to begin with. Not losing money due to your greed is better than wiping out your entire exchange balance. People always think about what profit they can make, but ignore the part where the losses are a more realistic outcome.
