Today I saw that kind of "coincidental transfer": A sent some money to B, half an hour later C sent a transfer back to A, and the comment section started conspiracy theories... I now prefer to break down the path first: Is it the same source of funds splitting, passing through an aggregator/bridge, or simply market making/clearing moving funds around. Many "coincidences" on-chain are actually just processes being too long, looking like mutual hints, but in reality, they are just automated scripts running.

By the way, the heated debate over that "yield stacking" strategy, my understanding is roughly the same: the more nested the path, the worse the interpretability, and the easier it is to hide risks in the last hop. People who have been rug-pulled twice tend to see unclear transfer chains and first think they are hints for me to get overleveraged... Small positions can be checked out.
