Bitcoin rewards mined in March 2010—now moving after more than 16 years from long-dormant wallets—have triggered fresh debate over whether the earliest coins could be tied to Satoshi Nakamoto. On Saturday, multiple addresses that together held about 600 BTC (worth roughly $48 million) transferred funds after an inactivity stretch spanning well over a decade and a half, according to onchain data reviewed by Cointelegraph.

The latest movement is getting attention because it falls within the period when Nakamoto was still active in Bitcoin’s early development. But blockchain sleuthing by Whale Alert points to a different conclusion: the company says it found no link between these specific mining blocks and Nakamoto.

Key takeaways

• About 600 BTC moved from dormant Bitcoin addresses after more than 16 years, with Cointelegraph tracing the activity to onchain monitoring reports.
• Whale Alert attributes the funds to block rewards from March 2010, when the per-block subsidy was 50 BTC.
• Whale Alert says its research cannot connect any of the 12 relevant mining blocks to Satoshi Nakamoto.
• The same incident builds on Whale Alert’s earlier work that covered seven of the rewards, now expanded to all 12.
• Lookonchain previously identified seven miner wallets tied to the March 2010 mining period, reinforcing the timeline.

Whale Alert expands its mapping of the March 2010 rewards

Whale Alert’s follow-up research, as reported to Cointelegraph, identifies all 12 reward events behind the dormant funds. The transfers originate from Bitcoin blocks mined in March 2010, when each mined block paid a 50 BTC subsidy. Over time, that subsidy has been reduced through Bitcoin’s scheduled halving process.

Most recently, the subsidy fell in April 2024, when Bitcoin’s block reward decreased from 6.25 BTC to the current 3.125 BTC per block, following Bitcoin’s 2024 halving. While that historical note doesn’t change the origin story of the dormant coins, it helps contextualize why coins mined in early 2010 were so much larger per block than today’s issuance.

Whale Alert previously analyzed only seven of the rewards and said in an X post that those blocks were not mined by Nakamoto. This latest work extends the company’s tracing to the full set of 12 reward blocks connected to Saturday’s wallet activity.

Where the “Satoshi” speculation comes from—and why Whale Alert disputes it

Speculation intensified because the moved coins are “Satoshi-era” rewards—mined while Nakamoto was still participating in Bitcoin communications and development. Nakamoto’s involvement didn’t end abruptly; the individual continued to be present in the project through 2010 and then gradually withdrew. Cointelegraph previously reported that the last known communication dates to April 2011.

However, Whale Alert argues that timing alone is not enough to claim a link to Nakamoto. A Whale Alert spokesperson told Cointelegraph that none of the blocks tied to the 12 rewards can be connected to Satoshi based on its research. In other words, although the coins are old enough to keep the mythic connection alive, Whale Alert’s mapping does not support the origin claim.

For traders and long-term holders, the practical takeaway is that “old coins” and “Satoshi-era” are not the same as “Satoshi coins.” The distinction matters because narratives about Nakamoto-linked holdings often feed into heightened speculation, even when the underlying evidence is absent or inconclusive.

Inactivity broke: test-transaction pattern and wallet behavior

Whale Alert also provided interpretive context for how the transfers unfolded. The company noted that one of the 12 reward payments moved several blocks before most of the others. Whale Alert suggested this sequencing resembles a test transaction—followed by later transfers from the remaining related addresses—rather than a single coordinated sweep.

That behavioral detail matters because it influences how observers read the motive behind dormant-wallet activity. A test transaction implies the sender may have been verifying rules or pathways before moving larger amounts, whereas a single immediate consolidation typically points to a different kind of operational intent. Without access to private keys or additional offchain context, onchain pattern analysis is the closest available lens.

Cointelegraph also notes that Lookonchain previously identified seven miner wallets that moved 350 BTC after about 16.5 years of inactivity, attributing those wallets to March 2010 mining. Taken together, the overlap in timing supports that the dormant activity is tied to the early mining subsidy period, even if the participants remain anonymous.

What to watch next as “early coins” come back online

These movements are a reminder that Bitcoin’s early distribution still occasionally reappears on public ledgers—sometimes after extraordinary inactivity. Even when those events are not linked to Nakamoto, they can still matter: large-value transfers from long-dormant addresses can shift sentiment around supply dynamics and may drive short-term speculation about whether more old holdings will move.

For now, the key uncertainty is whether additional related wallets—connected to other early mining outputs—will remain silent or follow this pattern. Investors and traders should watch for follow-on transactions from adjacent early-era addresses and for further onchain attribution work that either corroborates or refines the “which blocks were mined by whom” questions.

Lee opens the picture with a funeral, or, rather, a small family piling into their car to get to the funeral venue. Wife and mother Mi-ok (Jeon Do-yeon) wonders if she’s wearing the right dress, and the shoes she has chosen, a pair she hasn’t worn in a long time, are already pinching her feet. Her husband, Ho-seok (Sul Kyung-gu), says little—so little that it’s clear he’s filled with dread over whatever awaits him at this upcoming, obviously unhappy social event. Their extremely quiet young son (Jung Seop) sits in the back seat, amusing himself by dangling an empty chip bag out the window like a windsock. “It’s flying,” he says, just before letting it go—he’s not the only one feeling the oppressiveness of that car ride.

It’s never expressly spelled out who this funeral is for, but we can intuit that it’s one of Ho-seok’s former work colleagues. It turns out that Ho-seok is one of many workers who not so long ago lost his job at a large corporation, SP, and he hasn’t yet recovered, either financially or emotionally. Mi-ok is doing the best she can—she holds down a menial factory job—but her husband’s depression and excessive drinking is getting to her. By chance, in the funeral home parking lot, she meets a handsome stranger, Sang-woo (Zo In-sung), who moves his very expensive car when Mi-ok believes her wedding ring, having slipped off her finger, has rolled beneath it. It turns out that Sang-woo’s wife, Ye-ji (Cho Yeo-Jong), is making a documentary about, as she puts it, “the personal lives of laborers.” Ye-ji is thrilled to have found Mi-ok and Ho-seok as subjects—she’s particularly interested in the melancholic Ho-seok, who, she believes, could be the dramatic key her project. But she and Mi-ok also genuinely like each other and strike up a friendship. Possible Love traces the tangled dynamics between these four characters, while also flirting with uncomfortable questions about the moral quandaries that can arise in any filmmaker-subject relationship.

Coins mined in Bitcoin’s earliest era have finally stirred after more than 16 years of inactivity, prompting fresh speculation that they could be tied to Satoshi Nakamoto. According to on-chain analysis highlighted by Cointelegraph, 12 dormant Bitcoin addresses collectively moved 600 BTC on Saturday—an amount currently valued around $48 million.

While the timing has fueled “Satoshi-era” narratives, Whale Alert’s research claims it found no evidence linking the transactions to Nakamoto. The platform says the moved funds trace back to block rewards earned during March 2010, when Satoshi was still actively involved with the project’s early development and communications—before gradually stepping back.

Key takeaways

• On-chain data reviewed by Cointelegraph shows 12 Bitcoin addresses moved a total of 600 BTC after more than 16 years of dormancy.
• Whale Alert traced the 600 BTC to mining rewards paid across 12 Bitcoin blocks in March 2010, each originally issued as a 50 BTC subsidy.
• Whale Alert says none of those blocks can be connected to Satoshi Nakamoto based on its analysis.
• Prior work by Whale Alert covered only seven of the rewards, while Lookonchain had earlier identified seven miner wallets moving 350 BTC.
• The fact that the coins were mined while Nakamoto was still involved is driving attention—but “same era” is not the same as “same owner.”

Early blocks, long dormancy, and a sudden wake-up

The renewed activity centers on a cluster of very old wallets that had not shown movement for over a decade and a half. Cointelegraph reports that 12 addresses collectively moved 600 BTC after more than 16 years. Whale Alert, a blockchain transaction tracking platform, said the amount originated from rewards mined across 12 distinct Bitcoin blocks.

For investors and on-chain observers, these kinds of “awakening” events matter because they can create a brief narrative spike: dormant supply can look like potential future sell pressure, even when no immediate market impact is confirmed. In this case, the key question is not just that the coins moved, but where they came from—and who may have controlled them.

Whale Alert told Cointelegraph that its research did not find a link between the mined blocks and Nakamoto. This point is important: speculation often increases when activity occurs during a period associated with Nakamoto’s involvement, but attribution claims require more than chronology.

Whale Alert expands its tracing from seven to twelve rewards

Whale Alert’s updated work reportedly traces all 12 block rewards to Bitcoin blocks mined in March 2010. At that time, the protocol paid a 50 BTC block subsidy per block. Since then, the subsidy has been reduced repeatedly through halvings; the most recent reduction referenced in the report came in April 2024, when the block subsidy fell from 6.25 BTC to 3.125 BTC per block.

The analysis also builds on Whale Alert’s earlier effort. Cointelegraph notes that Whale Alert had previously examined seven of the rewards and said it identified those blocks as not mined by Nakamoto. In the updated accounting, Whale Alert now extends its tracing to cover the remaining five rewards as well.

Independent on-chain analytics had already surfaced part of the story. Cointelegraph says Lookonchain initially identified seven miner wallets that moved 350 BTC after 16.5 years of inactivity, attributing the funds to mining activity in March 2010. Taken together, the different layers of analysis underscore a consistent theme: these were mining rewards from early blocks—not some later token swap or unrelated transfer.

Why “Satoshi-era” is a tempting narrative—and a weak proof

The movement drew attention largely because March 2010 sits squarely in the period when Satoshi Nakamoto was still active in Bitcoin development and communications. Cointelegraph points to Nakamoto’s involvement continuing through 2010, with the last known communication dating to April 2011.

However, the editorial distinction here matters: “mined during the time Nakamoto was around” does not automatically mean “controlled by Nakamoto.” Whale Alert’s spokesperson emphasized that none of the blocks associated with the 12 rewards could be connected to Nakamoto based on its research.

Cointelegraph also reports a behavioral detail that further complicates simple attribution. Whale Alert said one of the rewards moved several blocks before most of the others, suggesting the early transfer pattern could align with a test transaction preceding the rest of the movements. In other words, even if multiple rewards originate from the same month and subsidy era, the way the coins were handled over time may reflect operational behavior rather than a single, easily identifiable owner.

What to watch next after these long-dormant transfers

When ancient Bitcoin moves, the immediate on-chain fact is clear—coins changed hands from addresses that had been silent for years. What remains uncertain is the economic intent behind the transfers: whether these movements represent consolidation, internal housekeeping, or preparations that could later involve liquidation.

For readers monitoring these developments, the most practical next step is to track where the 600 BTC ultimately flows after the initial movement, and whether any portion returns to new dormant addresses or heads toward exchanges. The “Satoshi” question may remain speculative without stronger evidence, but the real signal for market participants will be the downstream path of the coins and how quickly—if at all—the revived supply reaches liquidity.

Bitcoin mined in 2010 moved from long-dormant addresses after more than 16 years, reigniting speculation over a possible link to Satoshi Nakamoto.

Twelve addresses holding a combined 600 Bitcoin (BTC), worth about $48 million, moved the coins on Saturday after more than 16 years of dormancy, according to onchain data reviewed by Cointelegraph.

Whale Alert, a blockchain transaction tracking platform, said the 600 BTC came from rewards mined across 12 Bitcoin blocks and that its research found no connection to Nakamoto.

“None of the blocks can be connected to Satoshi based on our research,” a spokesperson for Whale Alert told Cointelegraph, tempering speculation around the origins of coins mined while Bitcoin’s pseudonymous creator was still active.

Whale Alert traces all 12 mining block rewards

Whale Alert traced all 12 rewards to Bitcoin blocks mined in March 2010, when each block paid a 50 BTC block subsidy. The subsidy has since been cut in half four times, most recently in April 2024, when it fell from 6.25 BTC to the current 3.125 BTC per block.

The findings expand on Whale Alert’s earlier analysis of seven of the rewards. It said in an X post on Sunday that those seven originated from blocks it had determined were not mined by Nakamoto.

Lookonchain, an onchain analytics platform, had also initially identified seven miner wallets that moved 350 BTC after 16.5 years of inactivity, saying the wallets earned the coins through mining in March 2010.

Satoshi-era doesn’t mean Satoshi’s Bitcoin

The movement attracted attention partly because the coins date to a period when Nakamoto was still actively involved with Bitcoin.

Nakamoto remained involved in Bitcoin development and communications through 2010 before gradually withdrawing from the project, with their last known communication dating to April 2011.

Whale Alert noted that one reward moved several blocks before most of the others, saying the pattern was consistent with a test transaction before the remaining transfers.
