Former Mt. Gox CEO Proposes Bitcoin Hard Fork to Reclaim 79,956 BTC from 1Feex Address

On 28 February 2026, former Mt. Gox CEO Mark Karpelès released a draft plan for a Bitcoin hard fork aimed at recovering 79,956 BTC tied to the 2011 exchange hack and held in the “1Feex” address. The proposal would redirect the coins, worth over $5.2 billion at current prices, into Japan’s court-led civil rehabilitation for Mt. Gox creditors, but has reignited debate over immutability, potential chain splits, and short-term downside risk for Bitcoin’s price.
