I've been watching the chain late into the night recently, and I find myself getting more and more anxious: block builders, bundles, these things—how much do retail investors really need to understand so they don't get taken for a ride? Honestly, I think just knowing enough is fine—understanding that your transactions don't necessarily "enter blocks in the order you submit," and that forking/rollbacks are often not mystical—they're just someone packing a bunch of transactions into a more convenient position. There are two main things you can do regularly: don't aggressively push into pools with low liquidity, and don't set your slippage too high; if you need to make large trades, split them up or use protected private channels, and don't expose all your intentions in the public mempool. As for deeper construction details... I’ve looked into them, but they don’t necessarily make you more profit, and they can easily lead to overthinking.

By the way, recently in the group, there's been a debate about privacy coins/mixing and compliance boundaries. I just find it quite disconnected: on one hand, shouting "privacy is a right," and on the other, fearing that your account might be flagged for risk control at any moment. Anyway, I’m now more focused on on-chain behavior itself, speaking less about stories, and just trying to survive.
