Recently, many people have been using "on-chain data" as real-time ECG, but what you're seeing might already be a bit outdated. Nodes have their own synchronization speeds, RPCs also queue and limit traffic, and indexers scan first then organize; when there's congestion or reorganization, the displayed data is often a half-beat late, or they might even give you a "seems correct" version first. To put it simply, what you think is monitoring the market is actually watching a replay.

So now, when I see anomalies, I don't get excited right away. I compare with two more RPCs or browsers, especially for large transfers or mints that just went out. By the way, I was reminded of the recent NFT royalty disputes—many people are arguing over "how to split secondary sales," but the transaction records themselves can be delayed or missed by a few minutes... emotions, however, are always real-time. Anyway, I just treat the "data source" issue as part of the risk.
