Recently watching on-chain transaction playback, it’s a bit like waiting in line at a convenience store to buy rice balls: you think you’ve scored a discount, but in the end, two people in front and behind you clip your “bargain,” turning it into their transaction fee.

The thing about sandwiches is honestly not mysterious; it’s just that you’re too impatient to place an order, your slippage is too loose, or the pool is too shallow, and someone else moves the price a step faster and sells back.

I used to be tempted by those “risk-free arbitrage” screenshots, but then I thought it was pretty funny—actually, most of the time we’re just working for more professional bots.
Recently, social mining and fan tokens—this “attention is mining” trend—have become popular. I think it’s quite similar: you think you’re mining, but you might be fueling someone else’s traffic funnel.
Anyway, I now prefer to trade less, set limit orders whenever possible, because that impulsive move is really the most expensive.
