Two Dormant Bitcoin Addresses Activate With $6.9M After 16 Years - Bitcoin Foundation

The addresses date to 2010, putting them among Bitcoin's earliest holdings. One transferred about $3.4 million in BTC, while the other became active, according to U.Today. Both had remained inactive since Bitcoin's early development period, making the close timing and matching balances distinctive features of the activity.

The precise estimates were $3,442,939 for the first address and $3,442,129 for the second. The first address's entire 50 BTC holding had been worth just $3 in Bitcoin's early days, giving that activation a documented historical dollar comparison as well as a dormancy interval.

Whale Alert was the blockchain tracking platform behind both observations. It assigned each address a 50 BTC balance and a 16.2-year period of inactivity, the two measurements at the center of the story.

Historical Significance

The historical label comes from the addresses' 2010 origin. Bitcoin's pseudonymous founder, Satoshi Nakamoto, was still active in the network's development during that early period, when the network had relatively few miners and users.

Bitcoin initially paid miners a 50 BTC block reward. Each of the newly active addresses held an amount matching that original reward, giving the balances a recognizable connection to the network's earliest mining period.

A separate case documented in 2025 involved the address identified as "18eY9o," which held 4,000 BTC worth approximately $446 million. After more than 14 years without activity, it transferred 150 BTC, valued at around $16.6 million, to a new cryptocurrency address.

Recent Pattern

The platform also tracked several older Bitcoin addresses that became active in October. On October 17, Whale Alert tracked activity involving old addresses holding 248 BTC and 167 BTC, valued at about $20.24 million and $13.65 million, respectively.

An address holding 500 BTC became active on October 20 after 10.7 years of dormancy, valued at about $41.54 million. Two days later, on October 22, Whale Alert identified another dormant address holding 170 BTC, valued at roughly $14.38 million, that had been inactive for 13 years.

Market Context

CoinGecko recorded Bitcoin down 6.04% over 24 hours on November 13. The address activity was therefore drawing attention during a falling market, with the later BTC price recorded at 07:21:54 UTC.

The owner's motive remained uncertain. Possible explanations discussed for older wallet movements included reorganization of funds or recovery of the wallet by its original owner or relatives. Bitcoin community figure Nicholas Gregory also suggested that some early holders could be moving coins to more secure addresses because of concerns about future quantum attacks.

The sequence of dormant address activations continues to draw attention as Bitcoin's market evolves, with these early holdings representing significant value from the network's formative period.
