Recently, I saw new L1/L2 incentives to boost TVL again, and in the group, older brothers are both rushing and complaining, "Mining and selling," which I can also understand... Sometimes it's not that the strategy is bad, but that your swap hasn't yet entered the pool, and someone else has already bundled and taken it away, making it feel like "it's gone again." I used to think it was my mistake, but I gradually accepted that in the blockchain, who goes first or second isn't entirely decided by your confirmation click.

Honestly, how much do retail investors need to know? I think remembering three things is enough: First, after you send a transaction, it might be "bundled" together and inserted into a block, and the order isn't random; second, pools with low liquidity, high volatility, and newly launched incentives are most vulnerable to sandwich attacks, so don’t treat them like savings; third, if possible, use privacy/protection RPCs or aggregator modes to prevent sandwich attacks, and don’t set slippage too rigidly. I personally follow a gardener’s approach: keep the main position in a "safer" place, and only chase incentives with smaller positions, so if I get sandwiched, it won't ruin my mindset.
