These past few days, looking at the liquidation list has made me a bit nervous: if the oracle feed is a half beat slow, your position is like waiting for a bus, the bus hasn't arrived but the rain has already started... The on-chain price actually changed earlier, but the feed is still stuck at the old level, and the result is that when you need to add margin, you don't react, or even though you've already recovered, you're still liquidated at the old price, which feels pretty unfair. To put it simply, don't just focus on the K-line; before opening a position, I now check the oracle update frequency, whether there are backup sources, and tighten leverage a bit—staying alive is more important than winning a single trade. By the way, the recent debate over privacy coins/mixing compliance also feels similar: information is delayed or obscured, and in the end, it's the ordinary people who take the fall... Anyway, that's all for now.
