Recently, I saw everyone talking about block builders and bundles again, and I feel retail investors really don't need to force themselves to become researchers. To put it simply, you just need to know: when you click "market price / large slippage / chasing trades," your transaction might not be included in the block in the order you want. It could be packed, front-run, or sandwich attacked, especially during busy times on the chain when memes are flying around.

My bottom line is threefold: avoid going on-chain with large amounts of funds without precautions (break into smaller parts, set limit orders, don't rush), don't force transactions during congestion, and if you do, accept that the transaction price might look ugly. As for how to choose builders or how to bundle transactions... just knowing they exist is enough, don’t expect to outsmart MEV.

Also, some mainstream public chains are upgrading or maintaining, and the community is guessing whether projects will migrate or not. I’ll just look at the on-chain depth and transaction density first. Whether they migrate or not is their business; I’ll just prepare my orders in advance and not let emotions make me click too fast.
