Just paid my tuition again: confidently rushing into a pool, only to find out as soon as I made a trade that I bought into "air"... Basically, I was only paying attention to the slippage setting and didn't check the depth first; the order book was as thin as paper, and a slight shake of my hand pushed the price up. Later, when I reviewed, I realized that the timing of placing orders is also very important—rushing makes it easier to get slapped in the face; placing orders in several parts and waiting for the momentum to return is actually more stable.

Thinking about the recent blockchain games with inflation + studio rushes, causing the coin prices to spiral downward, it's actually the same principle: on the surface, it looks like "price drops," but underneath, liquidity and support have disappeared. In the future, I’ll be slower, first checking how deep the water is before deciding whether to jump in. Feedback is welcome... I’m still practicing too.
