In the cryptocurrency world, the well-known "80/20 rule" phenomenon indicates that 80% of the time the market may perform blandly, while the real profit opportunities are concentrated in 20% of the time. Due to the unpredictable nature of the market's sharp fluctuations, investors must always maintain a certain level of market participation. This does not mean waiting to fully invest when prices rise, but rather holding a heavier position when the market is rising and maintaining a lighter position when it is falling, acting in accordance with the trend.

However, many people adopt the opposite strategy. They tend to gradually increase their positions as prices rise, and this inverted pyramid style of operation makes their positions heavier at high points. When the market reverses, they often suffer huge losses due to their heavy positions. This behavior is strikingly similar to gambling: betting small when in profit, accumulating some profit; but when heavily betting, a market downturn can wipe out all the accumulated gains.

There is a classic saying in market investing: "Be greedy when others are fearful, and be fearful when others are greedy." At market highs, when most people rush to buy, one should decisively sell to relinquish chips; and at market lows, calmly pick up chips. This contrarian investment approach, though against human nature and uncomfortable, aligns with market rules. After all, those who profit are often the few investors who can operate contrary to human instincts.

Greed usually stems from the hope of compensating for past losses through the continuous rise of a certain asset, thus unwilling to sell when prices keep rising, which is typical gambler's psychology. True wisdom lies in understanding that one only needs to catch the middle portion of a fish; the head and tail are not worth chasing excessively. Learning to decisively let go at the right time can lead to steady profits.
