600 Bitcoin Mined in 2010 Move After More Than 16 Years

What Happened To The Dormant Bitcoin?

Twelve Bitcoin addresses holding a combined 600 BTC moved their coins on Saturday after remaining inactive for more than 16 years, drawing attention because the assets were mined during Bitcoin’s earliest period. The transferred Bitcoin was worth roughly $48 million at the time of the movement. Blockchain tracking platform Whale Alert traced the coins to 12 separate mining rewards generated in March 2010, when each Bitcoin block paid miners a 50 BTC subsidy. The transfers immediately revived speculation over whether the addresses could have belonged to Bitcoin creator Satoshi Nakamoto, who was still active in the project during that period. Whale Alert said its analysis found no evidence connecting any of the 12 blocks to Nakamoto. “None of the blocks can be connected to Satoshi based on our research,” a Whale Alert spokesperson said. The conclusion is important because old Bitcoin frequently attracts outsized attention when it moves, particularly when the coins date back to 2009 or 2010. But the age of a mining reward alone does not establish that Nakamoto mined it.

Where Did The 600 BTC Come From?

Whale Alert traced all 12 transactions back to blocks mined in March 2010. At the time, Bitcoin’s block subsidy was 50 BTC, meaning the combined 600 BTC represented the full rewards from 12 mined blocks. That reward structure looks very different today. Bitcoin has undergone four halvings since then, with the most recent in April 2024 reducing the block subsidy from 6.25 BTC to 3.125 BTC. Earlier blockchain analysis had initially identified seven of the dormant miner wallets, which moved a combined 350 BTC after roughly 16.5 years without activity. Whale Alert later expanded the analysis to all 12 block rewards. The transaction pattern also offered a clue about how the holder may have approached the transfer. Whale Alert said one of the rewards moved several blocks before most of the others, a sequence consistent with someone sending a test transaction before transferring the remaining funds. That behavior would fit a cautious owner dealing with assets that had not moved since Bitcoin’s experimental early years, although blockchain data alone cannot establish who controls the addresses or why the coins were transferred.

Investor Takeaway

The movement is notable because of the coins’ age, not because there is evidence they belonged to Satoshi Nakamoto. The more relevant market question is whether the 600 BTC are simply being reorganized between wallets or are being prepared for sale.

Why Do Old Bitcoin Transfers Attract So Much Attention?

Bitcoin mined in 2010 belongs to a small pool of coins created when the network had relatively few participants and Nakamoto was still directly involved in development and communications. Nakamoto remained active through much of 2010 before gradually withdrawing from the project. The creator’s last known communication dates to April 2011. That timing means movements from early miner wallets can quickly generate speculation about whether Nakamoto-controlled coins are becoming active. The distinction matters because a confirmed movement from wallets linked to Bitcoin’s creator would carry far greater market and historical importance than a transfer by another early miner. In this case, Whale Alert’s research argues against that interpretation. The episode also shows how little information a blockchain transfer provides about motive. A move to a fresh address can reflect improved custody, wallet consolidation, an inheritance process, preparation for collateral use or an eventual sale.

Could The 600 BTC Be Heading To Market?

There is no evidence from the transfers alone that the holder intends to sell the Bitcoin. The immediate destination of old coins is often more informative than the initial movement. Transfers into known exchange deposit addresses can suggest possible selling activity, while movements between private wallets may simply reflect custody changes. That distinction becomes more important with large dormant balances because early miners acquired their Bitcoin at effectively negligible cost compared with today’s market price. Even a partial sale can therefore represent an enormous realized gain. The 600 BTC involved here are meaningful in dollar terms, but still small relative to Bitcoin’s overall daily trading volume. A direct sale would not necessarily create a major market shock, though traders often watch dormant-wallet activity because it can affect sentiment. For now, the strongest conclusion is narrower: a group of mining rewards untouched since March 2010 has become active, but the available blockchain research does not connect those rewards to Nakamoto. The next transfers may provide a clearer indication of whether the holder is merely reorganizing the coins or preparing to use them after more than 16 years of inactivity.
