I used to be a bit paranoid, thinking "I only look at the chain" was enough, focusing on block builders, bundles, mempool setups, and researching whenever I saw someone say they got squeezed... Later, I realized retail investors really don't need to turn themselves into semi-engineers. To put it simply, I understand about three points: 1) The transaction you send may not be included in the order you think; others can bundle and include it together; 2) Large and high-slippage orders are more likely to be targeted; 3) Use private transactions, limit orders, or batch trading when appropriate, don’t force it. Recently, someone called on-chain large transfers and hot/cold wallet movements on exchanges "smart money," I also glance at it, but now I remind myself: it might just be arbitrage or repositioning, don’t get too caught up. Anyway, I trade high-volatility pools, first clearly define the entry conditions, accept losses if things go wrong, and believe reviewing past trades is more reliable than guessing "who's buying."
