Recently, I've seen people watching on-chain large transfers and hot/cold wallet movements on exchanges, and as soon as there's any activity, they say "smart money is coming." Honestly, I feel indifferent about it... To be clear, those might just be repositioning, consolidation, or risk control actions—don't automatically jump to conclusions.

How much should retail investors understand about blockchain builders/bundles? I think enough is enough: know that your submitted transactions may not be included in the block in the order you see; they might be bundled together and added to the chain at once. If you place obvious arbitrage or stop-loss orders, on-chain participants and bots can see them in advance, front-run, and slip past you. What you can do is limited: avoid chasing prices during extreme congestion; split large orders into batches, set acceptable slippage; use reputable wallets/routers, and avoid clicking on strange signatures. If you want to delve deeper into builder ecosystems and various strategies, that's for professional players. Small funds don't need to push themselves to become researchers.

My colleague also asked me, "Should I also look at bundle data to catch signals?" I can only say... it's better to first understand your position sizing and risk layering, and handle the rest from there.
