Ethereum shot up to $3000 and soon after plummeted in a straight line. Many people didn't have time to react, and the market had already completed a round of efficient "precision harvesting." This tactic is not new: prices range-bound at key resistance levels, creating the illusion of a breakout, only to turn around and drop rapidly. Recently, we opened two short orders at the two positions of 2980 and 3000, precisely understanding this tactic of "finding opportunities at resistance level rebounds."

The problem is that these high-volatility operations are fraught with risk. No matter how beautiful the strategy's win rate is, it cannot withstand a single judgment error or a suddenly emerging black swan event—profits accumulated in the early stages can be wiped out in an instant. Not to mention that in market sentiment-driven trends, rationality is often the first thing to be cast aside.

So at this point, the more volatile the fluctuations and the more intense the long-short confrontation, the more necessary it is to add a "stable support" to asset allocation. This is not only to diversify risk, but more importantly, to remain calm and maintain a mindset during market chaos. Many experienced traders do this: they operate aggressively while leaving enough room for stablecoins.

The beauty of stablecoins lies in their provision of a value anchor that is detached from price fluctuations. When you are trading in high-volatility assets like ETH, you can promptly convert some profits into stablecoins, allowing you to secure your gains and avoid the shrinkage caused by sudden reversals. At the same time, while waiting for signals at the next key level, holding stablecoins enables you to quickly respond to opportunities without being trapped in a range-bound market. This way, you can both seize opportunities and protect the earlier gains.
