I’ve been diving for a long time, but I still can’t help but say this: stuff like block builders and bundles—retail investors really don’t need to learn it to the point of “being able to write it themselves.” How do you know when it’s enough? Honestly, it comes down to two things. First, the transactions you send may not end up getting included in blocks in the order you want—especially when you’re chasing hype / trending opportunities, your slippage is too large, or you use market orders to go all-in; it’s very easy to get sandwiched in the middle as fuel. Second, don’t be superstitious about “seeing large transfers on-chain / exchange hot and cold wallets moving = smart money is about to pull”—those signals are often just narrative material, and whether your specific order can get filled at a good position is a completely different matter.
