Sixteen-year-old bitcoin worth $8.5 million moves from an address that had spent 549 other coins
About 100 bitcoin mined in July 2010 moved for the first time in more than 16 years, a stake now worth roughly $8.5 million. Whoever moved them can now sell them, though no sale shows on the record and both new wallets sat untouched a day later.

What happened
- The coins trace to two mining rewards created in July 2010, one of 50 BTC and one of 50.02 BTC including fees, according to CoinDesk.
- Wednesday's transaction folded in six small later deposits and split the total into 10 BTC at one new address and about 90.02 BTC at another.
- The same address had spent 200 BTC in August 2015, 100 BTC in December 2017 and 249 BTC in March 2018, leaving the 2010 payment untouched each time.
- Bitcoin traded at about 6 cents when the coins arrived in 2010, putting the whole holding's value then at roughly $6.
Compiled by The InvestorSomething wrong?How this is made
Why it matters
- constraint The 549 coins spent from this address between 2015 and 2018 make it hard to count the move as lost supply returning, because someone was using the address as recently as 2018.
- exposure A full sale would put roughly $8.5 million of coins on the market, at most one eight-hundredth of the block Galaxy sold for a single early investor in 2025.
- precedent Galaxy Research counts this transfer in a wider 2026 pickup in dormant-coin activity, so each new old-coin move will be weighed as part of a trend whose total neither report gives.
If both new wallets stay quiet, Crypto Briefing wrote, the transfer "will likely end up as a security upgrade by a very patient early miner" [20]. The other possibilities are the first leg of a sale, or a sale arranged for estate planning. That second route has a precedent. Galaxy confirmed in July 2025 that it sold more than 80,000 BTC for an early investor as part of an estate-planning strategy [12]. Satoshi Nakamoto does not belong on the list. The coins date from the years Nakamoto was active, but CoinDesk says their age does not establish a connection [10].
CoinDesk explains the attention old coins get this way: some may have been treated as lost, and a transfer shows someone can still spend them [19]. This address fits that story poorly. Its 549 BTC of spending between 2015 and 2018 [13] came out of other payments. Bitcoin records each incoming payment separately, so one can move while another sits for years [6]. Galaxy Research first flagged the move [11]. "This address has been somewhat active in the past, but these specific coins have not moved since 2010. We track the coins," it said on X [5]. In my view, whoever spent from this address in 2018 could have spent the 2010 coins then as well. The public record does not show whether that is the same person who moved them on Wednesday [19].
Size also argues against treating this as an overhang. One hundred coins against more than 80,000 is about 0.125%, or one eight-hundredth [14]. The larger number is a floor, so the true share is smaller still. The dollar value does not quite add up either. At the $82,500 price Crypto Briefing cites [16], 100.02 coins come to about $8.25 million [18], while the $8.5 million figure [15] implies roughly $85,000 a coin [17].
Crypto Briefing also reported that Galaxy Research's tracking places the transfer within a wider pickup in long-dormant bitcoin moving during 2026 [21]. Any supply case would have to be built from that total, because a wallet this size cannot carry one. I think Wednesday's move was safekeeping by whoever controls an address that was spending coins in 2015, 2017 and 2018 [4]. That view is wrong if either new address sends coins to a known exchange deposit address, the signal Crypto Briefing names [20]. None had gone to an exchange when it reported [9]. The test has a gap. Galaxy sold the 2025 block on the investor's behalf [12], and a sale handled by a desk that way need not start with a deposit to an exchange.
What to watch
- Galaxy Research's 2026 count of long-dormant bitcoin on the move, and whether that total grows large enough to compare with the 80,000-plus BTC it sold for one investor in 2025.
- Any trading desk confirming a sale for an early holder, as Galaxy did in July 2025; that is how the last large block of old coins became public.

About 100 bitcoin (100.02 BTC) mined in July 2010 moved on Wednesday after more than 16 years without moving.
- [2]
CoinDesk traced the payment directly to two mining rewards created in July 2010, one worth 50 BTC and the other 50.02 BTC, including fees.
- [3]
Wednesday's transaction combined the old holding with six tiny later deposits and sent 10 BTC to one address and roughly 90.02 BTC to another.
- [4]
The address spent 200 BTC across two transactions in August 2015, another 100 BTC in December 2017 and 249 BTC in March 2018; the separate 100.02 BTC payment from July 2010 remained unspent throughout.

"This address has been somewhat active in the past, but these specific coins have not moved since 2010. We track the coins," Galaxy Research said on X.

Bitcoin records incoming payments separately (UTXOs), allowing a wallet to spend one payment while leaving another untouched, so an address can remain active while some of its coins sit still for years.
- [7]
Bitcoin traded around 6 cents when the address received the coins, putting their market value at approximately $6 at the time; the comparison describes appreciation, not what the holder paid.
- [8]
Both receiving holdings remained unspent when CoinDesk checked Thursday morning.
- [9]
Shortly after the transfer, none of the coins had been sent to an exchange or used for anything else.
- [10]
The coins date from the Satoshi era, when Satoshi Nakamoto was still active, but their age does not establish a connection to Nakamoto.

Galaxy Research, the research arm of Galaxy Digital, first flagged the movement on X.

Galaxy confirmed in July 2025 that it sold more than 80,000 BTC for an early investor as part of an estate-planning strategy.
- [13]
The address spent 549 BTC in other payments between 2015 and 2018.
- [14]
The 100.02 BTC transfer is about 0.125% of the more than 80,000 BTC Galaxy sold in 2025, roughly one eight-hundredth, and less given the 80,000 is a floor.
- [15]
The 100 BTC are now worth roughly $8.5 million.
- [16]
At the time of the transfer Bitcoin was trading near $82,500, and the coins were valued at roughly $8.5 million.
- [17]
The $8.5 million valuation implies a bitcoin price of roughly $85,000.
- [18]
At $82,500 per bitcoin, 100.02 BTC is worth about $8.25 million.
- [19]
Old holdings attract attention because coins long absent from trading can become available to sell again; some may have been treated as lost. A successful transfer shows someone still has access to spend them, but the public record does not reveal whether that person is the original owner or intends to cash out.
- [20]
If either of the two new addresses sends coins to a known exchange deposit address, that would point toward a sale; if both stay quiet, the transfer "will likely end up as a security upgrade by a very patient early miner."

Galaxy Research's tracking places this transfer within a wider pickup in activity from long-dormant Bitcoin during 2026.
