Ethereum successfully recovered after an early adjustment, with a single trade profit of $1900. In the current bear market environment, this result is even more valuable. Summarizing a key lesson: when trading major cryptocurrencies, you must control the leverage ratio. Staying within 5x is a relatively safe upper limit — even if you get caught, it's usually just short-term volatility, giving you enough time and space to wait for a rebound. Exceeding this leverage ratio significantly increases the risk curve. In a bear market, market volatility is relatively controllable, but black swan events are hard to predict. The advantage of a low leverage strategy is that it can withstand larger pullbacks, maintain a more stable mindset, and is less likely to be liquidated. This is more worthwhile than pursuing short-term gains with high leverage.
