Recently, I saw someone bragging about high leverage again, saying "I'm watching the price, not afraid," my first thought was: you're watching the exchange price, but the liquidation is based on the price fed by the oracle... If the feeding price gets delayed by ten seconds, and the market drops sharply then bounces back, you didn't have time to add margin, but the oracle's "confirmation" of the low point is a half-second late, and your position gets liquidated anyway. Looking back at the candlestick chart, you'd think you were wronged. What's even more frustrating is that some protocol liquidation bots run faster than you can click, everything on the chain depends on the order of operations, and emotionally, it really feels discouraging. Anyway, whenever I see high APY and layered L2 subsidies, I first think: this chain is cheap and fast, but is the feeding price, cross-chain, and node reliability trustworthy? The problem isn't necessarily in the interest rate, but in the "latency." For now, it's better to sleep a few less hours for peace of mind.
