I've been lurking in the group for a long time, and whenever everyone starts talking about block builders and bundles, I get a headache. I still can't help but say: retail investors really don't need to treat it as a research topic... You just need to understand that "it affects trading volume and slippage/being sandwiched" is enough. To put it simply, a bundle is when someone packages a series of trades and hands them to the builder, aiming to get priority on the chain or to sandwich your order to earn some spread. There are only a few things we can do: avoid large orders in one go, avoid rushing in during low liquidity, and use protective/private channels when possible (don't ask me which one is the best, I can only observe while using). If the trades look suspicious, just pause and review. Recently, there's been talk about tax increases and tightening/loosening of compliance. I feel the most direct impact is the change in deposit and withdrawal expectations—everyone becomes more anxious and afraid of missing out, which makes it easier to be "arranged" on the chain... Anyway, my interactions are slower now, my hand gets tired, but at least I’m less anxious.
