Recently, I was reminded again: when spot prices rise, I want to sell; when contracts shake, I want to add; in the end, either I can't hold on or I get liquidated. To put it plainly, position management boils down to one thing: only use the money you can sleep soundly with to enter the market, and treat the rest as if you've never seen it... I now directly set a "loss limit" in advance; once reached, I stop, even if prices continue to rise later. Outside, Layer 2 is still arguing over TPS, fees, and subsidies over which is stronger. I, on the other hand, focus first on who holds the permissions, how to stop if something goes wrong, and whether the audit is written in plain language.
