Recently, I saw everyone talking about "block builders, bundles," and honestly, how much do retail investors need to know? My personal threshold is: knowing that the transactions you send may not be included in blocks in the order you want, they might be bundled together and processed at once, or even when you click a swap, someone else might be sandwiched in the middle. That’s enough for me to adjust my mindset—don't always focus on "why didn't my trade execute" or "why did the slippage increase." Sometimes, it's not that you're slow, but that the chain's bundling logic is just like that.

What really needs to be done isn't complicated: for large amounts, split them into smaller parts; don't set the slippage too wildly; use private channels when possible (at least don’t put all your intentions into public pools to be watched). Going further to study which builder is more aggressive or which bundle is more clever… that’s a bit beyond my low-frequency level, and it’s easy to get more eager to trade frequently the more I learn.

Also, in the past couple of days, that main chain is upgrading/maintaining, and the group has started guessing whether projects will migrate or not. I’m actually more concerned about fluctuations in gas and confirmation times before and after the upgrade—don’t rush in and get stuck with a transaction for half a day, adding more lines to my cost ledger… That’s all for now, gotta hold back a bit.
