The third time I thought I “found a bargain” on the chain, I checked the transaction path and it basically turned out to be paying someone else's tuition... That kind of sandwich is really disgusting, you think slippage is market fluctuation, but honestly someone saw you in advance and casually took a cut. Arbitrage is the same, I draw the line thinking there's an opportunity, but when I click in, I find the price difference has already been eaten up by bots, and all I can get are leftovers.

Recently, someone also used ETF capital flows and US stock risk appetite to explain crypto price movements. I also take a look, but for small trades like mine, the most direct risk is actually “your operation becomes someone else's fee.” Now I just slow down, chase less, and try to place limit orders, avoiding rushing in during the busiest times... For now, this is the plan—fewer mistakes, the better.
