A Bitcoin whale has moved 5,907.56 Bitcoin (BTC), worth about $383.6 million, after keeping the coins untouched for more than 8.6 years, according to blockchain analytics platform Galaxy Research.
In an X post on Thursday, Galaxy Research said the transaction occurred on July 16, 2026, at around 00:15 UTC. The Bitcoin was moved from a wallet that first received the coins on December 14, 2017. The funds were sent to a new, unknown wallet, but there is no evidence that the holder has sold the Bitcoin.
Blockchain analytics platform Lookonchain also flagged the transaction. “A BitcoinOG transferred 5,908 $BTC($382.67M) to a new wallet after being dormant for 8 years…..The OG received 5,908 $BTC 8 years ago when $BTC was trading at $16,865 and had held it ever since,” Lookonchain posted on X.
Galaxy Research described it as a whale-scale move because it involved more than 5,000 BTC. The transfer took place in Bitcoin block 958217 and moved the assets from the address with the tag “138EMx … .SReyiT ” to a new wallet using the bc1q format.
Bitcoin holdings now carry a huge profit
The transfer drew attention because of the substantial increase in the value of the holdings since they were first acquired.
Galaxy Research estimates that the whale acquired the Bitcoin at an average price of around $17,000 per BTC. With the holdings now worth approximately $383.6 million, the whale has made an estimated profit of about $285.52 million, representing a 291% gain over the 8.6-year holding period.
Bitcoin was originally held in an older wallet address beginning with “1” before being moved to a newer “bc1q” SegWit address. SegWit is a newer Bitcoin address format that supports modern wallet systems and can help reduce transaction fees.
Wallet linked to broader Bitcoin ownership lawsuit
Galaxy Research identified the sending address as “Noah Doe #27 · Salomon Client Dusted,” while the recipient wallet remains unknown. In short, the address is linked to wallets included in its investigation into the Noah Doe litigation.
The case involves an anonymous plaintiff seeking ownership of approximately 3.8 million dormant Bitcoin. The lawsuit targets more than 39,000 inactive Bitcoin addresses, including some believed to be linked to Bitcoin creator Satoshi Nakamoto. The plaintiff argues that the Bitcoin in these wallets may have been abandoned.
Transfer does not indicate a sale
Despite the size of the transfer, the transaction does not confirm that the whale is preparing to sell.
The funds were sent to an unidentified wallet rather than a known cryptocurrency exchange address. The recipient wallet has also not moved the funds onward, meaning the reason for the transfer remains unknown.
Large transfers from dormant Bitcoin wallets often attract attention because they can signal potential selling activity or changes in long-term custody arrangements. A Bitcoin whale is generally defined as an individual or entity holding at least 1,000 BTC.
For now, the 5,907.56 BTC remains in an unknown wallet. Until the coins move to an exchange or another destination linked to a sale, the transaction only confirms that one of Bitcoin’s long-dormant whales has suddenly returned to the blockchain.
