As all the other suggestions, I'd advise you not to partake in a pumping group. The only reason to check one out should be to get an insight on why a coin might be pumping after they signalled it. Do not buy into these coins as the users of the pump group will probably sell them within hours and leave you at a loss.
OP doesn't really know the risk of a pump and dump group. He just basically giving out some money for them and is literally helping them to scam you with your presence. That's why in the first place if anyone asks about these kinds of signal group we strictly tell them to avoid it at all cost because this will basically drain all of your hard earned money.
