I know this is an old thread, but there are some great pump groups out there now (and some shitty scammer ones too). There is a new discord group that uses a randomizer to select the pump coin from a user-selected list of coins so mods and others can't pre-pump. That is how you get screwed. If you are interested and want to check it out, you can here:
