Recently, on-chain small swaps are being snatched up everywhere, and many people say "This is an opportunity, follow along for sandwiches/arbitrage."

I'm increasingly feeling that the opportunities you see might just be other people's source of fees... especially with cross-chain transactions, where slippage plus delays stack up.
You think you're catching a bargain, but it turns into fuel for others waiting in line.

Layer 2 has recently started comparing TPS, fees, and subsidies, causing quite a buzz, but honestly, user experience sometimes just depends on those few seconds of confirmation and that small liquidity gap.
Arbitrage bots don't care about the mudslinging; they only care whether you'll get impatient and hit "confirm."

What I fear most isn't losing money, but getting stuck on the bridge or in routing, watching the price difference get eaten up completely while paying gas twice.
Anyway, my current approach is just one word: slow.
First, check if the pool is deep enough and if routing is straightforward, then decide whether to act.
Being slow really saves money.
