Recently, I've been obsessed with badminton. For many years, I was stuck at the intermediate level of 3.0, but I've decided to push towards 4.0. I unexpectedly discovered that what was limiting me wasn't my control of the racket, but my footwork. Fortunately, after practicing a few lessons with my coach, I've gradually found the feel for my footwork, and I'm delighted to notice an improvement in the quality of my shots during singles matches. Recently, I saw a title on Xiaohongshu that read "The Four Fundamental Logics of Playing Badminton," and I could relate to it. It suddenly struck me that this actually has a lot in common with Crypto investing. Fundamental Logic 1 - Move your feet first, then your hands (70% footwork, 30% technique) Feet are like the right target + the right position, while hands are more like candlesticks + operations. Fundamental Logic 2 - Relaxation is the prerequisite for explosion. Reasonable position + a mindset that isn't overloaded; don't rush to go all in, learn to wait, and avoid FOMO. Fundamental Logic 3 - Consistency of movement + control of landing points. Do you have a trading system, or do you trade purely based on intuition? Fundamental Logic 4 - Energy and rhythm logic: varying speed > constant speed. The market is mostly in a state of fluctuation and dead time; there is no such thing as continuous profit. You need to seize the brief moments of "explosion windows" - move like a maiden, be still like a rabbit. I had Claude create a graphic to make it easier for everyone to see. Lastly, I want to reflect that in this world, although the techniques may differ, the underlying principles are the same.
