Recently, the group discussed block builders and bundles again. Honestly, retail investors don't need to memorize the MEV paper. You only need to know two points: 1) When you click "market price / chase the rise and fall," you might get cut in line or sandwich attacked, so don't use too aggressive slippage, and don't rush in when liquidity is thin; 2) For large transactions, try to split them up or use protected routing / limit orders to reduce the space for others to sandwich you. As for how builders package bundles or who follows private flow... just get a basic understanding, don't be fooled into thinking "I understand this and can make a profit." The recent debates over staking / shared security are also intense. Earning stacking sounds great, but the underlying risk transmission can also stack up. If you can't keep track of liquidation points, don't force it. Anyway, I’ll just note down the parameters and watch gradually. The overall atmosphere in the group is still okay now. Everyone complains and jokes, but at least no one is calling for a all-in gamble.
