Keep in mind older transactions are pruned from the tree on most nodes. While you may see where a Bitcoin originated, not all intermediate addresses will be shown forever in some version of the Blockchain. That's not to say that someone somewhere doesn't have the full blockchain, so you should keep in mind that it depends on what blockchain you are viewing at the time of investigation.

- kordless 13y agoBased on current observations, I would assume they are and have for some time.
