Lately I keep hearing everyone talk about block builders, bundles, making it seem like if you don’t understand, you’ll get “eaten up.” I think retail investors only need to know these points: the transactions you send may not be included in the block in the order you want; someone might bundle a series of transactions together to insert (to profit from arbitrage/priority), so don’t dream of “buying first and selling later to make a little profit” on the chain. If you really want to act, use routes or private entrances with anti-sniping/protection features, don’t chase slippage, and don’t rush into hot pools. The rest, like the underlying auction mechanisms and who collaborates with whom… honestly, knowing doesn’t change much, staying calm is more useful. By the way, recently some places have tightened or loosened regulations and compliance, causing deposit and withdrawal expectations to shift, and on-chain “urgent orders” have obviously increased. The more urgent, the easier it is to be arranged; I’d rather take it slow.
