Someone asked me, how much can a delay of a few tens of seconds in oracle price feeding actually affect?

Basically, you think you still have some buffer, but the system already sees the price and has kicked you out of the liquidation zone, especially when volatility is high.
By the time you react and add margin, the on-chain "old price" hasn't updated yet or just updated, and the liquidation bot gets there first.
Don’t think of liquidation as "I just click manually," it’s more like an automatic door—once it’s triggered, it closes.

My current approach is pretty simple: don’t leverage to the max, leave some safety margin;
when the market is volatile, don’t overreact—better to miss out than to gamble that the price feed just happens to be friendly to me.
Recently, social mining and fan tokens have become popular again, and yes, attention can be mined, but what I care more about is whether someone is watching your permissions, positions, and liquidation lines when you’re distracted by the hype...
Anyway, I always revoke unlimited permissions first before doing anything.
