Recently, browsing on-chain data has been a bit surreal: clearly seeing a certain transaction "just happened," then two minutes later it seems like it never occurred… It only occurred to me later that what we see on the "chain" is actually data pushed to us by nodes/RPCs/indices, and occasional network congestion causes delays or even incorrect data. Indexing services can fall behind blocks, RPC rate limits, or nodes can be out of sync, all of which might make you think you've caught the first-hand info, but in reality, it's just a replay.

These days, there's also been debates about rate cut expectations, the US dollar index moving in tandem with risk assets—rising and falling together. I dare not rely on just one data source anymore: anyway, market sentiment moves faster than the API. My rough method is to run two RPCs in parallel for comparison; the on-chain drama is like a cat chasing a laser pointer or watching a delayed live broadcast—don't get too caught up… For now, that's how it is.
