I just saw those "coincidental transfers" again: A sends some money to B, and after two minutes B sends it back to C, looking like a signal trade. In the past, I would obsess over finding the "truth," dissecting the routing step by step: whether it's an aggregator splitting orders, cross-chain bridge relay addresses, market makers replenishing liquidity, MEV bots taking a quick profit and returning change... Basically, many of these are just side effects of the system trying to save on fees and avoid slippage, and when the paths get longer, they seem more mysterious.

But recently, I’ve stopped chasing explanations so much. On-chain, you can indeed trace out "explainable paths," and it can help you avoid some pitfalls, but more often it’s just random stacking: someone slips up, scripts retry, studios batch process transactions—especially in blockchain games, where inflation kicks in, studios flood the market, coin prices spiral, and on-chain transfers become more like noise. Anyway, now when I see "coincidences," I treat them as probabilistic events. If I can confirm it’s due to routing or MEV, I’ll look into it; otherwise, don’t exhaust yourself playing detective.
