Recently, I've seen everyone talk about block builders and bundling; retail investors actually don't need to force themselves to become researchers.

You only need to know one thing: some transactions are not added to blocks in the order you expect; others can bundle a bunch of transactions and insert them, usually to front-run, sandwich, or avoid being seen in the public mempool.
So don’t always believe that “placing a limit order is safe,” because that’s not how the chain operates…

My bottom line is: large amounts should be split into batches, don’t chase during the busiest times, use protected routing/private submissions if possible, and pause if you see the quote slippage suddenly become outrageous.
In plain terms, understanding “I might get front-run” is enough; how the builder ecosystem shares revenue or who collaborates with whom is too far removed for retail investors.

By the way, recently, the cycle of on-chain games with inflation and studio frenzy, which ultimately causes the token price to spiral downward, is playing out again—similar to this: if you don’t understand the rules, you can only treat liquidity and sentiment as fuel.
Anyway, I’d rather go slower than let others use me as an experiment.
