Last night I made myself laugh out of frustration: I was staring at the on-chain "a certain address is buying," but on my side it still showed empty, and it took over ten minutes to refresh... It wasn't until later that I realized, what you see on the chain isn't necessarily "the current state of the chain," it could be that the node/RPC you're using is queuing, rate-limited, or the indexer hasn't finished syncing yet. Basically, it's the same chain, but different windows are viewing it, and the delay can make you feel like you're watching a drama with live comments replay.

What's even more outrageous is that this delay can directly affect trading psychology: you think the funds just moved, impulsively place an order, but in reality, others have already finished moving, and you're just the last to know. Recently, we've been talking about rate cut expectations and the US dollar index fluctuating with risk assets, right? When macro conditions shift like this, on-chain data becomes even more "congested," and the more anxious you are, the easier it is to fool yourself. Anyway, I've learned my lesson: when I see unusual on-chain activity, I first wait and watch, switch to two different RPCs to compare, then decide whether to act, and stop being that person who takes delay as a signal.
