Data from Btcparser.com reveals that over 1,000 dormant Bitcoin addresses—wallets that had never spent funds since creation—became active in 2025, collectively moving 123,852.58 BTC worth more than $11 billion. The activity was heavily concentrated among wallets created between 2011 and 2014, underscoring the outsized influence of early Bitcoin adopters on on-chain flows.
July Spike: Single Entity Sold 80,000 BTC via Galaxy
The most dramatic event occurred in July, when a small cluster of wallets from 2011 transferred over 80,000 BTC, representing roughly two-thirds of the year's dormant-address spending. It later emerged that a single early adopter worked with Galaxy Digital to offload holdings originally valued at $9 billion but ultimately sold for about $7 billion due to market fluctuations. This pushed July's total to 83,865.75 BTC, more than the previous six months combined.
Monthly Breakdown and Pattern
Excluding July, monthly dormant spending ranged from 1,500 to 6,000 BTC. January saw 3,412.52 BTC from 88 wallets; February: 1,549.41 BTC (66 wallets); March: 2,145.06 BTC (67). Activity accelerated in April (4,681.14 BTC, 100 wallets) and May (5,798.34 BTC, 93 wallets), before a June lull (1,671.45 BTC, 43 wallets). August had the highest number of reactivated wallets (157) spending 9,062.74 BTC. September–November each recorded 2,500–2,800 BTC, and December closed with 3,607.62 BTC, including two Casascius physical Bitcoin redemptions totalling 2,000 BTC.
Early-Era Wallets Dominate Spending Totals
Throughout the year, wallets created between 2011 and 2014 consistently accounted for the largest share of spending. Even sporadic reactivations from 2010–2012 addresses, such as a single coinbase reward move in February and five coinbase rewards in July, materially altered monthly totals. This pattern highlights the concentrated nature of Bitcoin's long-dormant supply: a small number of early adopters hold significant sway over on-chain metrics when they decide to move funds.
Market Implications
The 2025 data confirms that Bitcoin's dormant supply remains a potent market factor. While the total number of reactivated wallets was spread fairly evenly across months, spending volume was driven by a tiny subset of legacy addresses. As the network ages, these early wallets—rarely active but highly concentrated—could continue to cause abrupt shifts in liquidity and price dynamics. Analysts suggest that future awakenings from the 2011-2014 cohort will be closely watched for signs of further distribution.
