Recently came across a bunch of “on-chain arbitrage opportunities,” to put it simply, a lot of the profit you see is actually just the leftovers after someone else’s sandwich trade, and you still have to pay a fee to execute it. I’ve chased after a few before, but I found that the most stable “strategy” is actually: brew a cup of tea, wait for confirmation… if the market hasn’t moved away, losing your patience is what causes the biggest loss.

Cross-chain bridges get hacked again, oracles occasionally glitch with abnormal quotes—seeing this often makes me more convinced of “waiting for confirmation,” not out of fear, but because I don’t want to be a subsidy pool. Now I’ve made some “backup” for myself: at least review the same idea again, and ask myself from a different perspective whether I’m chasing noise. Anyway, whether I make a profit or not in the short term is really hard to say, but I try not to contribute to others’ fees.
