Recent years have seen many people ask me, "Do I need to understand block builders and bundling?"

I think retail investors only need to know about 70-80% of it: you don't have to be able to write a searcher, but you should understand that the transaction you submit may not be included in the block in the order you expect.
Someone can bundle, front-run, or eat your slippage completely. To put it simply, "transactions are not in a vacuum."
So I focus on two things: try to use reliable private channels / anti-MEV entry points, and don't be greedy with parameters (don't set slippage or gas too high).
When you see a bunch of large orders in the same direction on-chain within the same second, pull back first—don't hard compete.

These days, the attention rotation driven by Meme + celebrity shoutouts is back again.
Veterans advise newcomers not to take the last step—it's not about pretending to be mature...
You think you're chasing hot topics, but actually you're fueling someone else's bundle.

I still believe: data doesn't lie, but people can easily deceive themselves.
That's all for now.
