Lately, people keep asking me whether blockchain builders, bundles, and such are really necessary to understand... I think it's enough for retail investors to know "why you clearly clicked market order but the execution isn't what you expected." Basically, someone is packaging a bunch of trades, and the order of execution isn't necessarily in the sequence you see. Slippage, sandwich attacks, sudden order cancellations—all of these could be related to that. You don't need to learn how to code, but at least learn: don't blindly rush into thin order books, don't trust seemingly thick order books (fake liquidity is very common), use limit orders when possible, and try to avoid the busiest few minutes.

My mom asked me a couple of days ago, "Is a bundle like a package in delivery?" I said pretty much, just that this delivery might be someone quickly tearing off a layer of your packaging. By the way, hardware wallets are out of stock lately, and phishing links are everywhere. Really, don’t click impulsively; in trading, small tricks are not as good as improving your security habits first.
