TLDR
- A Bitcoin wallet from 2009 transferred 150 BTC worth $16.6 million after being inactive for 14 years
- The wallet originally mined 4,000 Bitcoin between April and June 2009, just months after Bitcoin’s launch
- The total holdings in the wallet are worth approximately $442 million at current prices
- The wallet was last active in June 2011 when it consolidated its Bitcoin holdings
- Some analysts suggest the move could be related to quantum computing security concerns for old Bitcoin addresses
A Bitcoin wallet that has been dormant since 2011 moved 150 Bitcoin on Thursday, marking its first transaction in 14 years. The wallet holds a total of 4,000 Bitcoin currently worth around $442 million.
A miner wallet 18eY9o, holding 4,000 $BTC($442M), just woke up after 14 years of dormancy, transferring 150 $BTC($16.59M) out.

The wallet owner mined most of the Bitcoin between April and June 2009. This was only months after Bitcoin’s network launched. Whale Alert reported the activity on social media platform X.
Data from Nansen shows the wallet sent 150 Bitcoin in a single transaction. The transfer was worth over $16 million at the time. Bitcoin was trading at about $110,604 on Friday.
The wallet was last active in June 2011. At that time, the owner consolidated 4,000 Bitcoin into one address. Back in 2010, when CoinMarketCap started tracking Bitcoin prices, the cryptocurrency was worth just $194.
Potential Larger Holdings
Blockchain analyst Emmett Gallic stated the whale may have once controlled 8,000 Bitcoin across multiple wallets. According to Gallic, the owner has been selling holdings from another address over several years. The current balance shows 3,850 Bitcoin after the recent transfer.

Data from mempool space indicates the wallet address received a total of 7,850 Bitcoin. The current balance reflects various transfers made over time.
This wallet is part of a pattern of early Bitcoin holders moving their coins. Another Satoshi-era wallet with 80,201 tokens started moving holdings to Galaxy Digital in July after 14 years of inactivity. That transfer was completed on July 16.
Security Concerns
Nicholas Gregory, a Bitcoin OG and Fragrant Board Director, raised concerns about quantum computing threats. He told CoinDesk that coins from 2011 may be vulnerable to quantum attacks. This applies specifically to addresses where public keys have been exposed.
Gregory suggested the transfer could be a security measure. “This could be a preemptive move to transfer coins to new, unexposed addresses that would be better sheltered from such quantum hacks,” he said.
Early Bitcoin addresses used different transaction types. P2PK addresses and reused P2PKH addresses expose public keys. These could potentially be targeted by future quantum computers.
Onchain data shows early holders have been taking profits at current price levels. Earlier this year, a wallet holding 80,000 Bitcoin sold its entire holdings. Galaxy Digital served as the broker for that transaction.
Crypto analyst Willy Woo noted in June that whales holding more than 10,000 Bitcoin have been selling since 2017. This selling has occurred despite growing institutional interest in Bitcoin.
The movement of old wallets sometimes signals that early holders are considering selling. However, analysts have stated that new buyers entering the market offset these sales. The rotation of holders from early adopters to new investors indicates market maturation.
