Lately, everyone has been arguing about which Layer 2 has higher TPS, lower fees, and more attractive subsidies.

I'm actually more worried about those "you think it's very safe" details: if the oracle feed is half a beat slow, liquidation becomes especially awkward.
When the market suddenly crashes, the on-chain price has already changed, but the lending side still calculates based on the old price.
You think your position can still hold, but the next update jumps straight to the new price, and the liquidation line seems to teleport right to your face.
The same goes for upward movements—others quickly add collateral or arbitrage, while you're still waiting for the quote to refresh.
Honestly, whether liquidation happens or not isn't always a matter of your judgment being wrong; sometimes it's just the time lag that keeps you stuck on the ground, rubbing against it...
Now I prefer to open less leverage, leave more buffer, and I’m even too lazy to touch protocols with slow oracle updates.
Let's see.
