Recently, I keep seeing people ask whether they should learn about builders and bundles. Honestly, for retail investors, just understanding that "trades don't necessarily enter blocks in the order you expect" is enough. Don't get caught up in the mindset of a miner or market maker; it's more of a reminder: for large swaps, grabbing new pools, or liquidating marginal positions, it's best to assume someone is watching your back. If you can use limit orders, avoid market orders; place orders in batches, and don't set slippage too high. If you're chasing new on-chain opportunities, use reliable routing or private submissions (at least don't broadcast your intentions openly in the mempool). I usually script everything to avoid getting too emotional with manual clicks. By the way, comparing on-chain yields to RWA or US Treasury yields looks pretty attractive, but how much of that yield is actually just the cost of "how the block gets ordered"... Anyway, I always factor in execution risk and don't just focus on APR.
