Recently, people keep asking me how much retail investors need to understand about blockchain builders, bundles, and such. To put it simply, you don't have to become an engineer; just know that "your transaction isn't necessarily confirmed on the chain the moment you click confirm," and that someone packing the transactions might manipulate it (by jumping the queue or inserting something). That's enough. So my current habit is: don't chase the hot chains, try to use reliable wallets with anti-clip settings/private forwarding, and regularly clear authorizations. It's better to be slow than to save a few cents on transaction fees.

These days, I've seen Layer 2 projects competing over TPS, fees, and subsidies, and it's quite lively... But after experiencing a few crashes, I care more about "what I signed, who I authorized, and whether I can revoke it." I set my goals lower: not chasing the cheapest or fastest, just avoiding pitfalls, and surprisingly, I stick with it longer. Anyway, avoiding one mistaken signature is a win.
