Recently, I've seen discussions on-chain about "sandwich" attacks and "arbitrage."

My first reaction isn't opportunity, but rather: Am I again paying others' fees...
You think you've picked up a coin on the ground, but in reality, someone has already wiped the surface clean in advance, so when you bend down, they casually snatch it away.

To put it simply, sandwich attacks are more like a "crowded trade" tax—whoever gets in first takes the slippage, and those behind just pay the bill.
My approach is a bit simpler: prefer to split trades into smaller parts, set more conservative parameters, or even just avoid chasing that move altogether, slowly adjusting cash flow and not being pushed by emotions.

As for the recent tax increase/regulatory trend in certain regions, I admit I was a bit slow—only rolling my eyes when I saw the group say fund inflows and outflows are about to change...
But overall, I feel the market tightening expectations, and everyone is more eager to "execute immediately." The more urgent, the easier it is for others to use you as a target.
Anyway, I plan to slow down the pace first.
