Dormant Bitcoin activity remained elevated in September 2026, with wallets created between 2010 and 2017 moving roughly 5,401.841 BTC in 94 recorded transfers, while another tally put the total at 5,419.45 BTC. The movements were valued at $457.23 million, and most of the moved bitcoins had been dormant for 12 to 16 years. The wallets involved ranged from nine years and two months old to 16 years and seven months. Wallets created in 2016 led by shifting 1,556.53 BTC across 13 transactions, followed by 2013 wallets that moved 888.91 BTC in 26 transfers. Fourteen transfers from 2010 wallets moved 600 BTC associated with exceptionally old block rewards. September activity was below August's 6,427.59 BTC but higher than July's total, according to the latest account. Large individual spends included 1,620.39 BTC on Sept. 6, while Sept. 5 recorded about 24 transfers. The source gives differing counts for the total activity, citing both 93 and 94 transfers, and says roughly 57 involved coins dormant for 12 to 16 years. The clustered wallet dates and orderly lot sizes are described as consistent with systematic consolidation by sophisticated holders, potentially including early miners reclaiming old rewards.
