Today I saw that kind of "coincidental transfer" on the chain again—A just received money and immediately sends it to B, B then goes to C, and the timing is tightly synchronized.

I used to imagine conspiracy theories, but later I found that breaking down the path isn't that mysterious: first, check if it's the same router/aggregator helping with the exchange, wallets seem like "transit stations"; then see if the funds come from the same deposit split, like doing batch moves; finally, compare labels, many are actually hot wallets of exchanges, bridges, or new protocol contracts running processes.
Recently, the main chain is undergoing upgrades, and everyone in the group is guessing whether they'll migrate.
I'm just watching the fund flow first, even if it's just a small test or exploratory move.
It's tiring, my eyes are dry, but it’s pretty satisfying when I finally connect the dots of the coincidences…
That's all for now.
