Lately, I keep seeing people talk about "on-chain coincidence transfers," like two unfamiliar addresses transferring the same amount back and forth within a few minutes, which makes people start to overthink.

Now that I have OCD, I tend to break down the transaction path: first, find out who the previous hop was and whether it was the same funds split off, then check if there's a big wallet address like a CEX hot wallet involved.
Yesterday, I also noticed a detail: 0x8a…f3 first transferred 1.234 ETH to 0x21…9d, and in the next block, it was transferred from 0x21…9d to a contract, with gas deliberately set to 21k, clearly not a "mistaken transfer."
By the way, these days, before and after some major chain upgrades/maintenance, people are guessing whether projects will migrate.
I think on-chain activity looks more like moving funds in advance, changing paths to hide traces; sentiment moves faster than data.
Anyway, I’m just watching for divergences.
