I'm a bit tired from watching the market all day, but I'm still here. Suddenly I thought about oracle price feeds: it doesn't seem like a big deal normally, but if the network stalls or the quotes are half a beat slow, it can be very awkward at the liquidation line — you might think the price hasn't reached the trigger, but the system could have already switched from "old price/new price" and liquidated you, or vice versa. If the market crashes early and the system hasn't reacted yet, catching up can feel like a knife attack. Basically, leverage is all about timing; price feed delays are like stealing a little bit of your safety cushion. Recently, hardware wallets are out of stock, and phishing links are everywhere. I'm now more inclined to keep smaller positions with more margin as a buffer, avoid staying up all night if possible — after all, life is more valuable than transaction fees.
