This is the third time I've seen someone ask "How much do retail investors need to understand about block builders and bundling?" Basically, you only need to understand enough to pay less in fees: when you click to make a transaction on the chain, you're not directly entering a block. Many times, your transaction will be bundled, front-run, or even sandwiched. You don't need to study complex mechanisms—just remember two points—don't chase orders recklessly during peak congestion, and don't give too much slippage; also, try to use routing/wallet settings with anti-sandwich features (at least don't leave everything at default). For large amounts, split into batches; it's better to be slow than lose money.

Recently, airdrop season feels like clocking in for work, with task platforms fighting back against botting and points systems going crazy. The chain is even more crowded, and failed transactions and tips burn up super fast... As someone who collects dust, I look at the tiny coins in my wallet as a reminder: don’t equate “understanding the principles” with “making money.” First, reduce unnecessary losses, and that’s enough for now.
