I used to be a bit paranoid, always saying "I only look at on-chain data," watching liquidity, routing, and trading slippage, feeling that these are the most real.

Later, I realized that even if the chain is clean, time value can quietly wear you down: buyers pay "rent" every day, and even if the market is stagnant, it still deducts; sellers seem to collect rent, but when big volatility hits, they hold tail risk close, making it hard to sleep peacefully.

So now I care more about: are you really racing against time, or are you working for volatility?
AI agents and automated trading have been hyped up recently, essentially just executing "plans" faster, but time value won't soften just because you're automated...
On the other hand, more on-chain interactions—authorization, routing, contract risks—may save slippage but also introduce safety pitfalls.
Anyway, I’d rather do less and not leave "stability" to scripts to gamble on.
