Two bitcoin addresses dormant for more than 16 years move 100 BTC worth about $6.9 million, mined in September 2010

Two bitcoin addresses that had not moved coins in more than 16 years transferred a combined 100 BTC on Friday, November 13, worth about $6.89 million, The Block reported, citing its own onchain data, the Mempool explorer and Whale Alert, which first flagged the moves on X.

Each address held a 50 BTC block reward mined in September 2010. Whale Alert estimated that each reward was worth about $3 when it was received. The first transfer went out at 4:08 a.m. UTC, and the second followed just over two minutes later. Both used the early pay-to-public-key format and sent the coins to newer native SegWit addresses.

By 4:48 a.m. UTC, about 59 BTC from the two transfers had been consolidated into a single new address, according to The Block. The owners, the reason for the moves and whether both addresses belong to the same person are unknown.

Old coins move from time to time. In July 2025, five 50 BTC rewards from April 2010 moved to new addresses, and in March 2024, 2,000 BTC from 40 mining rewards from 2010 were combined, The Block noted.
