Just now, I placed an order and got "snatched" again, which shook my confidence a bit... Later, I thought about it, retail investors don't actually need to research block builders and bundles to the level of academic papers. You just need to know: the transaction you send may not go directly into a block; it could be packaged and sorted in between. Whoever offers a more attractive "packaging fee" gets ahead; the result is slippage, execution price, or even being squeezed out without moving at all. For me, there are three practical points: don't set too tight a slippage; split large orders into smaller batches; try to use reliable private/protected routes (the less exposed, the better), and avoid directly competing with the public mempool. As for recent social mining and fan token schemes—"attention as mining"—it's basically a form of bundling: attention is packaged and sold to those willing to pay more. Retail investors shouldn't think of themselves as builders. That's all for now.
