How does pump signals work? Answer : it doesn't!
You can make some money in pump groups if you follow these rules :
1) Don't be naive (you won't become rich in a few seconds)
2) Don't be greedy (if you bought in the pump, sell quickly and don't wait for the price to moon and then crash) You can make about 20%-30%, but it is risky
3) Don't use all of your money on the pump group. You will be sorry.
4) The big groups are only there to take your money, the smaller groups pumps a little bit slower and you get enough chance to get out.
5) Lastly, IF you can get an earlier signal, without paying a ridiculous amount of money to get in the VIP club or "inner circle", you have a much better chance to make some profit.
I found this group that has early signal access for free :
