To become a trading expert, first of all, you need to learn to read the exchange rate of any coin/BTC, trade with Bitcoin as the currency base, and try to keep more and more Bitcoin in your hands, rather than more and more USDT! This is the true essence of cryptocurrency trading! If the ETH/BTC exchange rate rebounds to the range of 0.045-0.05 one day, I hope everyone will not hesitate to sell all ETH for BTC. And from now on, never buy ETH.
