These days, hot topics are changing so quickly.

Yesterday, it was all about Layer 2—who has higher TPS, lower fees, bigger subsidies—today, the narrative has shifted.
Honestly, attention is just liquidity; when everyone's eyes shift, on-chain slippage starts to resemble "harvesting":
If you chase after it, the transaction price gets pushed up, and by the next second, you look back and find you've been caught off guard.

I used to be quite stubborn, "I only look at on-chain data," thinking it wouldn't deceive me.
Later, I realized I could be fooled too: on-chain activity doesn't mean it's time to jump in; it might just be bots paving the way for you.
Now I force myself to add a layer of "emotional filtering"—if I see the timeline flooded with the same sentence or the same chart, I hold off and prefer to miss out.

My approach isn't anything fancy: before placing an order, I check if the slippage was suddenly suggested to be increased, or if the Gas fee is being pushed to unreasonable levels;
if possible, avoid market orders and use limit orders, split the amount into two parts, and test the waters with a small amount first.
Anyway, I’d rather be a bit slower than end up as sandwich meat every day.
