I spent the whole afternoon watching those "coincidence-like" transfers: A sends to B, B sends to C a few minutes later, and the amounts are similar... At first, I also thought it might be the same group laundering back and forth, but once I traced the path, it wasn't so mysterious. First, check if it's the same CEX hot wallet collecting retail investors, then see if the middle transaction is a routing/aggregation contract; many "multi-hop" transactions are actually just currency swaps + passing through LPs, or sometimes just gas refunds. Recently, before and after major upgrades/maintenance on mainstream public chains, these on-chain detours have increased, and everyone is speculating whether they will migrate. I actually think there's no need to rush into storytelling—just explain each hop as best as you can, and the remaining parts might be small corner alpha. It's tiring, but I still have to keep digging; anyway, I don't really plan to stop.
