Summary

  • A Bitcoin wallet that had not been used for over 8.5 years has moved 5,907.56 BTC, valued at around $383.6 million.
  • The Bitcoin was sent to a new wallet instead of a known exchange, indicating that a sale is not imminent.
  • Galaxy Research estimates that the value of these holdings has risen by approximately $285.5 million, a 291% increase since their acquisition in 2017.

A Bitcoin wallet that had been inactive since late 2017 became active again on Thursday, transferring 5,907.56 BTC worth about $383.6 million to a new address after more than 8.5 years of dormancy.

As reported by Galaxy Research, these coins were first received on December 14, 2017, and the transfer occurred in Bitcoin block 958217 at around 00:15 UTC. The firm calculates that the value of these holdings has appreciated by approximately $285.5 million, representing a 291% increase based on an estimated average purchase price of about $17,000 per Bitcoin.

Notably, the funds were moved to a previously unknown wallet rather than a recognized exchange deposit address, which does not suggest that the holder intends to sell the Bitcoin.

Galaxy Research linked the sending address to "Noah Doe #27 – Salomon Client Dusted," which is connected to addresses examined in the Noah Doe litigation earlier this year.

The Noah Doe lawsuit, detailed in a May 2026 report, involves an anonymous plaintiff claiming ownership of around 3.8 million dormant Bitcoin. The case targets over 39,000 inactive Bitcoin addresses, many of which are believed to belong to Bitcoin's creator Satoshi Nakamoto, arguing that these coins were effectively abandoned.

This transfer also converted the coins from a legacy address starting with "1" to a newer bc1q address format, which offers lower transaction fees and aligns with modern wallet standards.

A Bitcoin whale is typically defined as an individual or entity that holds at least 1,000 BTC. Since blockchain transactions are transparent, significant transfers are closely monitored for insights on whether major holders are accumulating, redistributing, or preparing to sell.

In December, long-term holders started shifting billions of dollars worth of Bitcoin after the asset surpassed $100,000, a change one analyst described as a "great redistribution" from early adopters to new owners.

"This year, Bitcoin has experienced an unprecedented amount of coins changing hands," stated CryptoQuant analyst J.A. Maartun to Decrypt. "I refer to this as the 'great redistribution,' where Bitcoin held by long-term holders has been transferred to new owners in several waves."

In January 2026, a wallet from the Satoshi era moved 2,000 BTC valued at around $180 million to Coinbase after remaining untouched since 2010. CryptoQuant's data shows that institutional "new whales" now control approximately $130 billion worth of Bitcoin, exceeding the roughly $126 billion held by long-term whales.
