No need to pay fees when the coins are old. Fees are there to prevent spam.

That's interesting! You made me read more about Bitcoin transaction fees (I found this http://bitcoinfees.com/ offering an explanation, although I can't appreciate its quality in this regard). I found this disturbing: "If any of the outputs (including any change) of your transaction are less than 0.01 XBT, then a fee of 0.0001 XBT is required."

Bitcoin is fungible up to a "Satoshi" fraction, yet the low-amount transactions are discouraged. Actually I'm not sure how it would be even possible to operate with amounts of 0.0001 Bitcoin or lower in the current condition (and that's one US Dollar at 10k USD/Bitcoin)!

If that was Satoshi, why would he move his btcs: is what way would this transcation make him more safe or anonymous?

interesting assumption, are there any particular reasons you think that was Satoshi (other than the media buzz) ?

A forum account linked to Satoshi posted today for the first time in several years to say that his identity was not that of Dorian Nakamoto. Plenty of people countered that the account could have been hacked, controlled by a site admin, etc. and have asked for further proof in the form of movement of some of the true Satoshi's stash of bitcoin. This could be that proof (or something else entirely).

Or, consistently with the persona in the article, it’s actually Satoshi claiming not to be Satoshi.

(Mind you, as much as a bitcoin-hater as I am, I find doxxing him distasteful. And I’m not even a total anti-doxxer, I just don’t see any justification for exposing his persona).

Gox coins.
