Recently, I've seen a bunch of people talking about blockchain builders, bundles, making it seem like retail investors will get "completely eaten up" if they don't understand. I feel that knowing enough to protect yourself is enough: you don't need to be able to draw the entire mempool process, but at least understand that your swap isn't "executed at the price you see once sent out," as it could be bundled, front-run, affected by slippage, and the transaction path can be manipulated. To put it simply, before placing an order, check the order book depth, tighten the slippage, and avoid using obscure routing; it's better to miss out than to become a liquidity donor.

The AI agent automated trading wave is also quite noisy; some people are touting "fully automatic passive income," while others are focusing on permission and signature security... I personally become more cautious the more automated it gets, giving as few permissions as possible. Watching these details for a long time makes my eyes a bit sore, and my neck stiff, so I’ll go move around first and come back later.
