The purpose of this server is to temporarily push the coin's price up to later collect profit from it. The way it works, everybody gets notified a week before the pump, so they have time to prepare. Then, after the countdown, everybody should purchase the same coin in the following minute. This makes the price spike, during which other people and bots will start buying the coin too, pushing the price even further. Later, the coins have to be immediately sold to take the profit. We repeat this process again and again with different coins.
