Recently, while looking at on-chain data, I was reminded once again: you think you're "watching the scene," but you might actually be watching a delayed replay. Slow node synchronization, your connected RPC acting up, index queues rebuilding—resulting in the same transaction showing as successful on one side, while on my end it still looks like it never happened... To put it plainly, the blockchain isn't lying; it's the window you're viewing that's lagging.

So I don't really jump to conclusions just because an address "suddenly shows no activity." I switch to a different entry point, wait a few more minutes, and then draw conclusions. Especially lately, with certain regions tightening and loosening regulations and taxes, everyone's deposit and withdrawal moods are very sensitive. The more sensitive they are, the easier it is to be influenced by "delayed on-chain" timing. Anyway, I prefer to confirm a little slower rather than rushing and falling into a trap.
