Why do you want to short a strong project?

On the first day, I made 50u with a small investment, on the second day I made another 50u, and on the third day I made 60u. I naively thought making money was this easy. As a result, I lost it back in two days, and now I'm down 500u. This account is about to be liquidated, and it's not too late to exit now. In the future, whenever I see someone wanting to trade cryptocurrencies, I will tell them not to play. In this game, nine out of ten people lose, and the one who profits is the market maker.
