I've recently (in the past few weeks) done like 25 pumps on groups (small, middle and big ones). First i thought this was all a dream and everybody would benefit from it. Unfortunately this isn't the case. That's why i want to share this with you guys. For 1 group i can say i made profit everytime (total times, 4 times). Between 100-500 USD , and average profit % of 40%.
So, if you want to make money, please watch and see for yourself which group is working. I would certainly start with small amounts to see if a group is good for you. For 1 I know which gives profit, i share with you:
