Recently, I saw someone talking about block builders, bundles, and so on. Honestly, retail investors really don't need to force themselves to become researchers. When I monitor the blockchain myself, I only keep three things in mind: the transaction you send may not be included in the block in the order you see; front-running/sniping is often not "you are slow," but someone packing a bunch of transactions together; and don't be superstitious about "click speed." Knowing these is enough to help you avoid many pitfalls.

If it really comes down to trading, I care more about not chasing blindly during high volatility, especially after a cross-chain bridge was hacked recently. When the community gets nervous, slippage, failure rates, and gas fees can all change suddenly. Also, oracles sometimes glitch, and now the community tends to say "wait for confirmation" at the slightest issue, which I understand... I’d rather be slow.

Anyway, my personal "priority order" is: first, stay safe; then trade. Don’t let others decide that order for you.
