Lately, I keep hearing people talk about block builders, bundles, and it seems retail investors don't really need to push themselves to become researchers. To put it simply, you just need to know: the transactions you send may not go "directly on the chain," they could be bundled or front-run, especially in hot pools or front-running scenarios. Don’t be naive and think that clicking confirm guarantees fair queuing.

My own "sufficient standard" is: for large or sensitive transactions, try to use private channels or set slippage, don’t run naked on the chain; for small daily transactions, don’t overthink it, so you don’t scare yourself. By the way, the current testnet incentives and points system are again raising people's hopes—everyone is guessing whether the mainnet will issue tokens… I also had a moment of wanting to quit and even uninstall my wallet for a couple of days, but thinking that watching the scene unfold is more fun. Anyway, don’t treat expectations as income.
