Last night I saw that kind of "coincidental transfer" again, A sends to B, B transfers to C a few minutes later, looking like someone is communicating in code.

Later I broke down the path, and actually many of them are explainable: exchange hot wallet consolidations, cross-chain bridge transfers, automated repayments of market-making/lending contracts, and even people moving positions on-chain while taking the fee money along for the ride.
To put it simply, don’t be fooled by the similarity in time and amount; first clarify address labels, interaction contracts, and next-hop destinations, many "conspiracies" turn into processes.

Recently, everyone has been comparing RWA, US bond yields, and on-chain yield products together, and I do too, but I care more about where the money comes from and how it goes out.
Even if the yields look similar, if you don’t understand the path, it’s easy to chase emotions.
Anyway, I’ll first write down the part I can explain, and what I can’t explain, I’ll just treat as noise—don’t force a story.
