We need to select a specific time and collectively pump price and not buy individually
And what on earth makes this a good idea??? Good, profitable pumps happen when there is good news released. A pump as you're talking about would just drop like a stone.
It is a good idea for somebody wanting to drop some coins and not liking the price. He will probably also buy back when it drops back.
Poeple like this only think about short term gains , they are not interested in the long future of any coin.
