Bitcoin wallets created years ago moved 626.74 BTC during the first five days of September 2026, with eight wallets dating to 2013 transferring 25 BTC each to crypto custodian Bitgo at block height 965625. The transfers occurred within 25 seconds of one another and appeared to involve the same entity, almost certainly one owner consolidating funds, according to the analysis cited from btcparser.com and Arkham Intelligence. September’s dormant-bitcoin activity amounts to 9.75% of August’s total so far. Wallets created in 2013 accounted for 346.07 BTC across nine transfers, while three 2011 wallets moved 90.50 BTC worth $7.22 million; that cache had originally been acquired for $285. The month’s average daily movement from old-school wallets is about 125.34 BTC, compared with an August average vintage-BTC spend of about 214.25 BTC.
