What is a wash? It means that a position is repeatedly inserted but cannot fall below. After two or three washes, everyone will sell when there is little profit, because they are afraid of another insertion. If the market really rises, they will chase it again, which will cause the dealer to kill you repeatedly. It will also cause you to lose money even though the market actually rises. In the final analysis, you can't hold on. If you want to do short-term trading, you can't do it without a few years of experience. Some people can't understand the technical indicators and don't know where to stop loss. It's pure gambling. $BTC
