I once tried to analyze an on-chain record that looked like a "coincidental transfer": A sends to B, then B sends to C a few minutes later, with similar amounts. At first glance, I thought it was money laundering.

But following the routing layer by layer, I found that it was actually an aggregator splitting orders + cross-pool token swaps, with B just being a relay contract, and the final transfer to C was still the same person's wallet...
Basically, it was just to reduce slippage by taking a longer route, making it look like a staged transaction.
Recently, during airdrop season, everyone is so caught up in task platforms and anti-witch-hunting that it feels like clocking in at work.
This kind of "path obfuscation" has become more common:
It's not a conspiracy, just a money-saving or rule-evading obsession.
Anyway, when I see a coincidental transfer now, I first map out the route before jumping to conclusions, or else I might wrongly accuse someone.
