In 2018 there used to be these tg pump groups with hundreds of thousands of ppl in them, and the operators would post a lowcap token that was listed on Bittrex, Poloniex, Binance, etc. The idea was that then everyone in the group would rush to buy the coin. If you had a scraper youd be early, etc. These coins often gained 100-200%. Even after the inevitable dump, these coins would still be higher than before the original pump, as many outsiders unaware of these groups had no idea that’s what caused the price move. Eventually the music stopped when ppl stopped buying these charts and also when operators accumulated too much supply beforehand to sell into these pumps.
