These past few days, I've been looking into liquidation-related stuff again, and I found that many people aren't actually being wiped out by "market conditions," but rather by oracles feeding prices too slowly, causing confusion... You think you still have some buffer, but as soon as the price updates, the liquidation line jumps right in your face, and before you can add more margin, you're taken out. To put it simply, those few minutes of delay are like standing at the elevator door with leverage positions—suddenly the door closes.

Recently, everyone has been complaining that miners/validators are making too much profit from MEV, and the ordering isn't very fair either. I can really empathize: price updates plus transaction ordering stack up, and retail traders really feel like they're watching the show from the last row. Anyway, I’m currently focusing on stablecoin strategies, and I’d rather earn a little less than have the liquidation line set further away—don’t count on being "fast with your hands."

There are many tutorials out there, but I prefer those that clearly explain the frequency of price feeds, sources of updates, and historical deviations, rather than a bunch of jargon filling the screen... That’s all for now.
