This morning, I saw a bunch of bundles entering blocks again.

Many people get panicked when they hear "block builders / MEV," but retail investors really don't need to memorize the process as a tutorial.
Honestly, knowing three things is enough:
The transaction price you see isn't necessarily "market natural matching"; sometimes it's others bundling transactions and accidentally including you;
When large transfers / dense same-direction trades appear, short-term fluctuations can be even stranger;
And also, don't casually use naked swaps, break down large orders as much as possible, and use protected routing if available.

Recently, with extreme funding rates, people in the group are arguing whether to reverse or keep squeezing the bubble.
I usually just think of it as "someone is using leverage to fight each other."
Seeing more bundles on-chain isn't surprising, but I won't interpret it as a trend.
Anyway, it's more important to control your slippage and transaction path than to guess who's behind the scenes.
For now, I'll review today's large transfer list again before breakfast.
