A Bitcoin wallet holding 600 BTC from mining rewards earned in March 2010 moved the funds over September 5-6 after more than 16 years of inactivity. The holdings were worth about $48 million at the time, broadly in line with an earlier estimate of $47.7 million. Whale Alert concluded after reviewing the blocks that they were not associated with Satoshi Nakamoto. The transfers reportedly began with a test payment before the remaining coins moved, and earlier on-chain reporting showed the funds were consolidated into two Native SegWit addresses without confirmed deposits into centralized exchange wallets. The transactions can reflect custody migration, wallet maintenance or other holder activity, and do not by themselves establish a sale.
