A 25-Second Burst Moved 200 BTC From 2013 Bitcoin Wallets

Dormant Bitcoin wallets moved 626.74 BTC worth more than $50 million during the first five days of September, according to Bitcoin.com News. The report said bitcoin traded between $76,000 and $82,000 during the preceding week. It also characterized the flow of long-idle coins as continuing, while saying the pace at which vintage wallets were becoming active had slowed compared with August.

Dormant Bitcoin Wallets Move $50 Million in September

The September 5 report detailed a concentrated series of transfers involving eight wallets first created in 2013. Each wallet shifted 25 BTC at block height 965625, with all eight transactions occurring within a 25-second window. Together, the transfers accounted for 200 BTC. The report said the timing and pattern appeared to involve the same entity and was almost certainly one owner consolidating holdings rather than eight unrelated owners moving funds simultaneously.

The transfers were discovered by btcparser.com, according to the report. Arkham Intelligence data cited in the report indicated that half of the 2013-era holdings were sent to crypto custodian Bitgo. The remaining half appeared to have been sent to Bitgo as well, although the destination address was not flagged by Arkham. The report identifies the observed destinations but does not state that the transferred bitcoin was sold.

The eight-wallet cluster represented a substantial portion of the month’s recorded dormant activity. The report said wallets dating to 2013 were September’s largest dormant spenders through September 5, accounting for 346.07 BTC across nine separate transfers. Outside the eight transfers associated with Bitgo, one additional transaction moved 146.05 BTC on September 2. That separate transaction brought the 2013-wallet total above the 200 BTC concentrated in the synchronized group.

September’s second-largest dormant event involved wallets dating to 2011. On September 3, three distinct transfers moved 90.50 BTC valued at $7.22 million in the report. It said 80 BTC had been held in wallets first created on November 5, 2011, when bitcoin was priced at $3.15. A third wallet, created on October 29, 2011, moved 10.5 BTC, with bitcoin priced at roughly the same level. The report calculated that the 90.5 BTC cache had risen in value from about $285 to $7.22 million.

Several other wallet vintages contributed to the first five days of September activity. The report listed 40.91 BTC moved from a single wallet created in 2012, 40.27 BTC moved from two addresses first seen in 2014, and 50 BTC shifted from a wallet created in 2015. It also recorded 58.97 BTC from two transfers involving wallets created in 2017. Taken alongside the 2013 and 2011 transactions, those movements formed the reported total of 626.74 BTC.

The report presents these transfers as movements from wallets that had been dormant for years. Its transaction descriptions focus on wallet ages, transfer sizes, timing and reported destination labels. For the 2013 cluster, the available description points to consolidation as the likely explanation. For the other transactions, the report records the transfers and their dates but does not provide a stated purpose for each movement.

How September Stacks Up Against August

The comparison with August is central to the report’s assessment of September activity. Through the first five days of September, the 626.74 BTC in reported dormant-wallet movements represented 9.75% of the total dormant BTC moved during August. The report described that proportion as evidence that vintage bitcoin spending had cooled, while also noting that September was still at an early stage when the figures were compiled.

Average daily activity provides another comparison in the report. During August, the average vintage BTC spend was around 214.25 BTC per day. For the first five days of September, the average daily spend from old-school bitcoin wallets was around 125.34 BTC. These are period-specific averages reported for two different windows: the completed month of August and the opening days of September.

The reported slowdown does not remove the significance of the individual transfers. The 200 BTC moved in the 25-second burst was the largest clearly grouped event described in the report, while the 90.50 BTC from 2011 wallets was identified as September’s second-largest dormant spender at that point. The 346.07 BTC associated with 2013 wallets also made that vintage the leading contributor to the month’s activity through September 5.

Dollar values in the report reflect bitcoin’s trading level at the time it was published. The article placed bitcoin’s weekly range between $76,000 and $82,000 and valued the 626.74 BTC moved during the first five days of September at more than $50 million. It separately valued the 90.50 BTC from the 2011 wallets at $7.22 million. The source’s figures therefore describe the value of the recorded movements during that reporting window.

What to Watch Next

The report offers a snapshot through September 5 rather than a complete monthly total. Its key reference points are the 626.74 BTC moved in the first five days, the 9.75% comparison with August’s total dormant activity, and the average daily figures of 214.25 BTC for August and 125.34 BTC for early September. Any later assessment of the month would require additional transaction data beyond the period covered by the report.

The wallet destinations described in the report also remain important to the account of the September transfers. Arkham Intelligence data cited by the source identified Bitgo as the destination for half of the 200 BTC from the eight 2013 wallets. The other half appeared to have gone to a similar destination, but the address was not flagged by Arkham. The report does not provide a confirmed sale record for those coins.

For readers following dormant bitcoin activity, the report distinguishes between a concentrated burst from eight 2013 wallets, a separate 146.05 BTC transaction from a 2013 wallet, three transfers from 2011 wallets, and smaller movements from wallets created between 2012 and 2017. That breakdown shows how the reported September total was assembled and why the 2013 cohort accounted for the largest share of activity during the period covered.
