But cant you just tell people the coins that you hold and have high sells up on bittrex that is the "coin" of the day. Always thought pump groups like this only benefit a select few members with the rest of the "members" doing their dirty work. 
That's what what many pnd groups do, and as someone who has witnessed it first hand I find it awful. The goal of this group is to be fair and to provide a way for anyone to make money. Not for just a select few to profit off the loss of others.
