Pump and dump

– refers to an illicit scheme involving manipulating the market price of a cryptocurrency by buying up the circulating supply in a short period of time, waiting for the market to react to the sudden price jump and then selling the purchased coins back into the market, capturing the profit.  Usually executed through coordinated group action using apps like Telegram.
