Recently, I've seen people arguing about NFT royalties again, basically meaning creators want to take more, and secondary sales are worried about liquidity being eaten... I'm actually more concerned about another kind of "invisible tax": slow oracle price feeds. You open a leveraged/borrowing position, thinking you're relatively safe, but when the market suddenly moves, the on-chain price hasn't updated yet. By the time it updates, you're already outside the liquidation threshold, and that little buffer simply doesn't exist. Even more outrageous is that you want to add margin but it's too late; once your order is sent, and the price feed refreshes, the liquidation bots are quicker than your script.

I'm now being honest: don't hold your position right at the line; when encountering a new pool, first check which oracle it uses, its update frequency, and how it handles anomalies. Better to earn a little less than to be sent out by "latency." What about you?
