Lately I keep seeing words like blockchain builders, bundles, and so on. To be honest, retail investors don't need to study enough to write code... My current "sufficient level" is: knowing that the transactions I send may not be included in the block in the order I confirm them, someone might bundle, jump the queue, or even pack a bunch of transactions together, so don’t get too excited when you see sudden fluctuations on the chain.

I only focus on two things: try to use reliable wallets/routes for large transactions, and before signing, take a second look at "what exactly did you authorize," then revoke permissions after use. Recently, cross-chain bridges have had issues, and oracles are reporting errors, and everyone is "waiting for confirmation." I’ve become more relaxed—slower, fewer operations, usually less loss.

It’s pretty funny. I set my goals lower: not chasing the best execution, not rushing to get the first bite, just hoping not to be exploited as a transparent person... and surprisingly, I’ve stuck with it longer. Anyway, my hot wallet only holds enough for meals, for now, that’s enough.
