I am very confused about something involving cryptocurrency. I occasionally see things talking about tracking some coins. But my understanding is that a "coin" in bitcoin or any other cryptocurrency is a quantity rather than some labeled and separately trackable thing. So while it is possible to track spends and transactions among wallet ids it is not possible to track a particular coin. Yet I often see articles that seem to say otherwise.

Do I have this wrong somehow? If so then exactly how?
