This move by BANK completely changed my gameplay approach.

Initially, I was aiming to climb the challenge ranking, and when I reached around 100,000 points, I was suddenly pierced by a needle, and my account balance immediately evaporated by 6U. At that moment, I felt something was off—after closely observing the market for a while, I noticed that the K-line fluctuations were quite regular, like oscillating back and forth within a specific range.

Since that was the case, I decided to switch strategies. I started doing repeated T trades: placing a limit order at 0.0828 to buy, while simultaneously placing an opposite order at the same price to prepare to sell. I kept flipping back and forth like this for several rounds, earning about 2.4U per trade consistently. After a few rounds, I not only recovered the previous losses but also gained enough profit to offset the small airdrop on an alternate account.

Of course, this method has obvious risks—it's only suitable for periods when the market volatility is particularly regular. Slightly unpredictable market movements can easily trap you.

Honestly, after this experience, I really don’t plan to participate in the challenge again; the losses are just too harsh.
