A Bitcoin whale that had been dormant for nearly 12 years roared back to life on September 29, 2025, moving 400.07908897 BTC (valued at approximately $45.6 million) from a wallet last active on November 20, 2013. According to data from btcparser.com, the transaction occurred at block height 916840, ending a silence of 11 years, 10 months, and 9 days.
Back in 2013, when the coins were tucked away, Bitcoin closed at just $590, meaning the stash was worth about $236,000. Fast forward to 2025, and the same amount is now worth $45.6 million, representing a jaw-dropping gain of 19,221.19%. This makes it one of the most successful long-term holds in cryptocurrency history.
Transaction Details
The whale didn't make a single transaction but instead split the 400 BTC into 27 separate outputs. Twenty wallets each received 15 BTC, six others received 15 BTC each, and one unique address received 10.07908897 BTC. Such a distribution pattern suggests the owner may be preparing for gradual selling or reducing the risk of single-address exposure.
Context: A Month of Awakenings
September has seen multiple long-dormant Bitcoin wallets spring to life. Earlier in the month, another whale from 2014 moved 500 BTC worth $57 million. Analysts believe these awakenings often coincide with market volatility or price peaks, as early adopters finally decide to take profits. With Bitcoin hovering near its all-time high of $115,000, the timing is notable.
Market Reaction
The transfer occurred during a weekend with relatively low liquidity, and the market reacted mildly. Bitcoin briefly dipped to $113,500 before stabilizing around $114,000. While a single whale transfer is unlikely to trigger a major sell-off, the cumulative effect of multiple aging wallets stirring could signal a shift in holder sentiment. For now, the market remains resilient, with traders monitoring whether more dormant coins will move.
