Recently, I've been looking at liquidation data again, and the more I look, the more I feel: the delay in oracle price feeds is really not just a "technical detail." If you leverage tightly, and the price drops sharply, the on-chain data might not have updated yet, and by the time the quote catches up, your position could be automatically liquidated according to the rules, leaving no window to "add some margin first"... In other words, sometimes liquidation isn't about misjudging the direction, but about losing to the time lag.

Layer 2 now competes daily on TPS, fees, and subsidies, and it's quite lively, but what I care more about is: where does the price feed come from, how often is it updated, and whether it gets stuck during congestion. Anyway, before opening a position now, I check the oracle update frequency first, and leave a bigger buffer in my position.

I no longer believe that "cheap equals safe." That's all for now.
