The core of creating an Ethereum contract is simply: stable profits. Instead of chasing every fluctuation every day to make a profit, it's better to keep a calm mindset and only act when it's the right time. The market operates daily, and rushing is unnecessary for a day or two. Frankly, no one can capture every tremor of the market, which is simply unrealistic. What is the true logic of making money? Recognize the direction, wait for the opportunity, act when it's time, and the remaining time is just waiting. Recently, Ethereum has attracted a new wave of users entering the market, and market activity is increasing. In the long run, this steady trading rhythm is much more cost-effective than blindly chasing the trend.
