Recently, I saw someone talking about blockchain builders, bundles, MEV, and so on. Honestly, retail investors don't need to force themselves to become researchers... Knowing how to "avoid pitfalls" is enough. My basic understanding is: the transactions you send out may not be included in the block in the order you specify; others can bundle them together and insert them all at once, so avoid on-chain operations that are obviously vulnerable (like chasing gains and selling, setting too large slippage, or writing your intentions too plainly). Use private/protected forwarding when possible; if you don't understand, just do less, split your transactions, and try small amounts first.

As for the recent speculation about whether projects will migrate before and after the main chain upgrade, I think it's also best not to be too "fate-oriented." Migration is a probability issue: consider the team's costs, where the users are, and where the on-chain liquidity is. As retail investors, it's better to guess less about the storyline and focus more on your own position's risk boundaries. That's the way to go for now.
