The most uncomfortable thing in the crypto world isn't actually the wild price swings. The real torment is watching it take off right after you sell.

Recently, I placed an order to sell some ETH positions, and the next day it dropped by 8%. I thought I was safe, but a week later, the price rebounded. Someone asked me if I wanted to buy back in, and I immediately placed a buy order. This simple operation taught many of my friends a lesson.

Actually, this is the essence of trading—daring to sell, daring to buy. I found that most people's real problem isn't that they don't know how to sell, but that they become completely timid after selling.

The two most common situations are: one, after selling, the coin price continues to fall, but they keep hoping for a lower point, only to see it rebound; and two, after selling, it rises again, but because they can't swallow their pride, they refuse to buy back at the same price, ultimately missing out entirely. I've fallen into both traps. In my early years, I often missed entire cycles because I was waiting for a "better opportunity," or I simply sat out out of "discontent."

Later, I developed a method: as long as your reason for selling no longer holds, or the overall trend still looks healthy, don’t hesitate—buy back boldly, even if the price is higher than when you sold.

What's the key? **The quantity remains the same, but the cash flow actually increases**. For example, if you sell 1 ETH at $3000, and then buy it back at $2800, you still hold 1 ETH, but your cash account has increased by $200. That’s real operation.

This mindset changed my view of the market. Don’t be hostage to right or wrong in a single buy or sell. True skill lies in adjusting flexibly according to market changes, rather than stubbornly sticking to one decision.
