Former Mt. Gox CEO Proposes Bitcoin Hard Fork to Recover $5.2B in Stolen BTC from 2011

Mark Karpelès, former CEO of Mt. Gox, has proposed a Bitcoin hard fork on February 27, 2026, to recover about 80,000 bitcoins tied to the exchange's 2011 theft and now valued at over $5.2 billion, The Block reports. The plan targets coins inactive for 15 years in related addresses and would introduce consensus rules allowing those funds to be spent using signatures from Mt. Gox recovery addresses, with distributions to creditors routed through the existing court-supervised restructuring process. Supporters view it as a narrowly tailored response to a specific theft case, while critics argue it could erode Bitcoin's immutability and set a risky precedent, The Block reported.
