A buddy is firmly bullish on ETH and has held on for several months; finally, in the past couple of days, he has turned the tide—his account unrealized gains are close to 1 million dollars.

To be honest, this guy is a typical long-term bull believer, not panicking when it drops and not getting carried away when it rises. After all, that's how the market works; no one can always lose, and no one can always win. Friends who trade contracts understand that a stable mindset is the most important factor.

However, speaking of which, this recent surge has indeed come on a bit strong. After a sharp rise, there are often hidden risks; it's time to take profits where needed and set good stop-loss lines. When the market is good, it's even more important to stay clear-headed and not let the profits you've made slip away.

The market is never short of opportunities, but once the principal is gone, it's truly gone. Everyone should grasp the rhythm and pay attention to risk control.
