Dormant Bitcoin Whale Moves $383 Million After More Than 8 Years

A Bitcoin wallet that had remained untouched since late 2017 sprang back to life Thursday, transferring 5,907.56 BTC worth about $383.6 million to a new address after more than 8.5 years of inactivity.

According to Galaxy Research, the coins were originally received on Dec. 14, 2017, and moved in Bitcoin block 958217 at approximately 00:15 UTC. The firm estimates the holdings have appreciated by roughly $285.5 million, representing a 291% gain on an estimated average acquisition price of about $17,000 per Bitcoin .

The funds were transferred to a previously unidentified wallet rather than a known exchange deposit address, providing no indication that the holder has sold the Bitcoin.

In the post, Galaxy Research identified the sending address as "Noah Doe #27 – Salomon Client Dusted," linking the wallet to addresses included in the firm's investigation of the Noah Doe litigation earlier this year.

According to Galaxy Research, the Noah Doe case, outlined in a May 2026 report , involves an anonymous plaintiff seeking ownership of approximately 3.8 million dormant Bitcoin. The lawsuit targets more than 39,000 inactive Bitcoin addresses—including many believed to belong to Bitcoin creator Satoshi Nakamoto , arguing that the coins were effectively abandoned.

The transfer also moved the coins from a legacy address beginning with "1" to a newer bc1q address format, which supports lower fees and modern wallet standards.

A Bitcoin whale is generally considered an individual or entity holding at least 1,000 BTC. Because blockchain transactions are public, large transfers are closely watched for clues about whether major holders are accumulating, redistributing, or preparing to sell.

In December, longtime holders began moving billions of dollars worth of Bitcoin after the asset climbed above $100,000 , a shift one analyst at the time described as a "great redistribution" from early adopters to new owners.

"This year, Bitcoin has seen an unprecedented amount of coins change hands," CryptoQuant analyst J.A. Maartun told Decrypt . "I call this the 'great redistribution,' during which Bitcoin held by long-term holders has been transferred to new owners in several waves."

In January 2026, a Satoshi-era wallet transferred 2,000 BTC worth roughly $180 million to Coinbase after the coins had remained untouched since 2010. According to CryptoQuant data, institutional "new whales" controlled about $130 billion worth of Bitcoin, surpassing the roughly $126 billion held by long-term whales.
