A dormant 2010 Bitcoin miner swept 600 BTC worth $47.84 million into fresh wallets on Sept. 5, the largest Satoshi-era awakening since January, as September's aged-coin flows cooled to about a tenth of August's volume.

Satoshi-era miner moves 600 BTC worth $47.8M to fresh wallets
A 2010-era Bitcoin miner shifted 600 BTC worth $47.84 million on Sept. 5, sweeping coins mined before the asset had a market price into newer wallet types.
The 12 transfers, spanning block heights 965639 through 965646, were flagged by btcparser.com and Whale Alert, with Arkham Intelligence tagging the originating addresses as a miner. All 12 legacy Pay-to-Public-Key addresses sent their full balances to fresh Pay-to-Witness-Public-Key-Hash wallets, a sweep pattern Blockchair scored 60 out of 100 for privacy.
The coins were coinbase rewards mined between March 2 and March 5, 2010, when network difficulty sat near 1 and blocks were solved with central processing units — before the first bitcoin transaction on May 22, 2010, and before the asset carried any market value. Bitcoin began trading that summer between $0.0008 and $0.08 per coin.
Where the 600 BTC lands next will determine whether the move points to distribution. A deposit to a centralized exchange would suggest potential sell pressure; a transfer to another private wallet would point to consolidation or a custody change. The destination P2WPKH wallets remained unflagged as of Sept. 6.
A Rare Awakening From Bitcoin's First Miners
2010-era spends are rare among dormant-coin movements. Of the 6,427.59 vintage BTC shifted in August, only two came from wallets created in 2010, according to btcparser.com. A sweep of this scale from a single early miner has not been seen since January, when a larger 2010 whale moved ten coinbase rewards in one block. Unlike that entity, whose rewards spanned mixed dates, this miner's coins came from consecutive days in the first week of March.
September's Dormant-Coin Flows Cool From August
The 600 BTC sweep arrived as September's broader aged-coin activity slowed. Across the first five days of the month, dormant wallets moved 626.74 BTC worth more than $50 million, with bitcoin trading between $76,000 and $82,000. That total represents about 9.75 percent of August's vintage-coin volume, and the average daily spend has fallen to roughly 125.34 BTC from August's 214.25 BTC.
2013 wallets have driven much of September's activity, shifting 346.07 BTC across nine transfers. Eight of those wallets, created in 2013, woke within 25 seconds of each other on Sept. 5 and sent 200 BTC to the custodian Bitgo, per Arkham Intelligence. A separate Sept. 2 transfer moved 146.05 BTC, while three 2011-wallet transfers on Sept. 3 shifted 90.50 BTC worth $7.22 million — a cache bought for about $285 when bitcoin traded near $3.15.
For the market, the open question is whether the Satoshi-era sweep and the broader uptick in aged-coin movement precede selling. Dormant-coin transfers to exchanges have historically preceded price weakness, while moves to private wallets often reflect custody changes or consolidation. With the 600 BTC still sitting in unflagged addresses, traders will watch for any onward transfer to a trading venue in the coming days.
