最近老看到大家聊区块构建者、bundle，搞得像不懂就会被“吃掉”。

I often see people talking about block builders and bundles, making it seem like if you don't understand, you'll be "eaten".

我觉得散户知道到这几条就够了：你发的交易不一定按你想的顺序进块，有人会把一串交易打包一起塞进去（为了赚差价/抢先），所以别在链上做那种“我先买再卖赚一点点”的梦。
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 them (to profit from arbitrage/front-running), so don't dream of "buy first, sell later, make a little profit" on the chain.

真要动手，能用的就用带防夹/保护的路由或私密入口，滑点别贪，别追着热点池子硬冲。
If you really want to act, use routes or private entry points with anti-sniping/protection, don't be greedy with slippage, and don't chase hot pools aggressively.

剩下更底层的拍卖机制、谁跟谁合作…说白了知道也改变不了什么，心态稳一点更有用。
As for the more fundamental auction mechanisms, who collaborates with whom... honestly, knowing these doesn't change much; staying calm is more useful.

顺带一提，最近某些地方加税、合规一紧一松，出入金预期一变，链上“急单”明显多了，越急越容易被安排，反正我宁愿慢点。
By the way, recently some places have tightened and loosened regulations on taxes and compliance, changing deposit and withdrawal expectations, and the number of "urgent orders" on-chain has obviously increased; the more urgent, the easier it is to be manipulated. Anyway, I prefer to take it slow.
