Let's set the record straight
👇
I can find no evidence that these coins were sent to Coinbase. Likely, this is referring to the "coinbase" reward.
The coins that moved today were directly spent from the "coinbase reward" of block 3654 on Feb 9, 2009.
"Coinbase" the company wasn't even around then.
This document lists thousands of addresses that were all "unspent-from" at the time of its admission to the court. They were all coinbase transactions.
Just because Craig claimed that this address belong to him, does not mean it belongs to him.
Again, that's also impossible to prove one way or another (there were multiple miners by February 2009), but chances are it was NOT Satoshi.
Early versions of the original Bitcoin mining software kept track of how many blocks it found over time, and inserted that number into the "extraNonce" field of block headers.
(shout out to satoshiblocks.info)
If we chart the "extraNonce" field w/ block number, we can see a clear pattern of a miner who was responsible for MOST of the blocks early on.
You can see other miners who were mining at that time too (the less-steep green lines). They mined lots of coins, but whoever was controlling the hashrate of the steep lines mined most.
The "blue" blocks are blocks in which the coinbase transaction is still unspent. "Green" means that the transaction has been spent.
So all of those blue blocks in a nice line are still unspent (aka likely Satoshi's coins).
