As first reported by @lookonchain, an old miner just moved coins mined on Jan 30, 2009 (close to 15.5 years ago). This is the addresses' only outgoing transaction.

Current value of the coins is $3,183,366. I checked and they did not move the Bitcoin Cash (yet -- its a piddly $17k).

I'm wondering who else could have been mining coins back then aside from Satoshi and Hal. I'm sure there were a handful of individuals.
