Lately, people keep asking me, “Do you really need to understand block builders and bundling?” I think retail investors knowing about 70–80% is enough: you don’t have to know how to write a searcher, but you do need to understand that the transaction you click may not go into the block in the order you expect. Someone can package it, cut the line, and swallow all of your slippage—plainly put, “transactions aren’t happening in a vacuum.” So I focus on two things: first, try to use reliable private channels / anti-MEV-type entry points; second, don’t get greedy with the parameters—don’t crank slippage or gas way up. When you see a bunch of big same-direction orders on-chain in the same second, back off first; don’t force a hard fight.

These days, that attention-rotation thing driven by Memes + celebrity trading calls is back again. Old players telling newcomers not to take the last step really isn’t just acting grown-up… You think you’re chasing what’s hot, but in reality you’re just providing fuel for someone else’s bundle.

I still believe this: data won’t lie, but people are very good at tricking themselves. That’s it for now.
