What are crypto pump and dump Discord Groups and Telegram?

In short: Crypto Pump and Dumps are Telegram Groups, Telegram Channels or Discord Server/Groups with many members who buy a coin (cryptocurrency like Bitcoin, Ethereum , USDT at Cryptocurrency Exchanges like Binance, KuCoin, etc.) at the same time and thus increase the price by up to several hundred percent within a few seconds. As the name suggests, the dump comes after this pump and the price falls again. That is it!
