An extensive onchain audit suggests with very high probability that the address was a consolidation address for a batch of genesis mining addresses which earned their (First Epoche) block subsidy of 50 #bitcoin. The timestamp information corresponds to a developmental phase where only Satoshi and Hal were known to be mining blocks.
You could conduct this audit yourself by analysing posts between Satoshi and Hal about mining and match the dates.
Here are a few links on mempool which are relevant to the audit.

Address alleged managed now by Hal's family which recently moved some large consolidated amounts as well as 5BTC to Kraken.

Some transactions happed around 2014 around the time of Hal's passing.
