After playing with ETH for these years, I have come to understand one thing: relying solely on luck to make a fortune in the market is not enough.

Where is the key? Two words - profit and loss ratio, plus win rate.

Many people pursue a high win rate, winning nine out of ten trades, which sounds great. But if you earn a little each time but lose a big amount once, in the end, it's all for nothing. The reverse is also true; even with a high profit-loss ratio, if you lose every time, you won't be able to continue.

Real profits come from raising both of these indicators simultaneously. Find opportunities where the risk is controllable and the potential returns are high, and then improve the accuracy of your judgments. This is the trading strategy that can lead to sustained profits. In simple terms, it's not about luck; it's about calculating probabilities.
