Well, investing in coins is too slow for my taste. It can take weeks before they take off and you see a profit.
If you want to multiply your investment, Pump&Dump yields a much faster profit.
These are the best Pump&Dump groups I've found in Discord:
Pump My Ride:
https://discord.gg/KWTehcaCommunity with Strategic Info and Tips for Interesting Coins - More Than 10 Pumps a Week
The Alt Pump:
https://discord.gg/TdsJzs2Chats in Multiple Languages - 2/3 Pumps a Week
Pump to the Moon:
https://discord.gg/r37XrhgInformative Community with Strong Signals - Pumps Every Other Day
They pump up the price of coins you invest into, with very nice profits.
All groups set targets for their pumps and as they also advise, NEVER buy above the target and dont be GREEDY. If done correctly you can make great profits, I personally make an average of +50% every pump.
You should be warning people more, a lot of these groups prebuy a huge stack before announcement of the pump and the followers end up buying those making the organiser and his buddies rich....
