lets start with one point-all pump and dump groups are basically shady,thieving instruments designed to
make one (or a group of the fastest guys) guy make money,as per some weird coincedence it is the admin of the group
the rest will always lose money,the laws of physics work in trading too-you can't get something without someone somewhere losing
so in this case the ones who are losing -the members of the group,again bar the shrewdest and the fastest ones
I don't even want to talk about the damage they do to the coins
some of which would never recover from the dump
I have read that pumps actually give life to dead coins.
