Tonight I saw that kind of "coincidence transfer" on the blockchain again: A sends to B, then B sends to C two minutes later, with the amount just right.

In the past, I would reflexively think someone is laundering, and my hand would itch to jump into the volatility pool's fee...
Honestly, I just get excited when I see a "story" in the path, afraid of missing out.

But these days, after the cross-chain bridge was hacked and oracles reported errors, everyone is "waiting for confirmation," and I’ve calmed down too.
Breaking down the coincidence, there are actually only a few common scenarios: post-cross-chain landing split accounts, OTC/market maker collection and redistribution, or arbitrageurs running a circle to recover small change.
Paths that can be explained clearly, I just note down and don’t add to my position;
Paths that don’t make sense, I set an exit condition first to avoid being led astray by my itchy hands again.
If it crashes, I’ll write a review later, for now, that’s how I’ll proceed.
