Former Mt. Gox CEO Calls for Bitcoin Hard Fork to Recover $5.2B in Lost BTC
Mark Karpelès, the former CEO of the now-defunct Mt. Gox exchange, is urging the Bitcoin community to consider an extraordinary step: a network hard fork to recover nearly 80,000 Bitcoin tied to the platform’s infamous hack.
In a proposal shared on GitHub, Karpelès suggested changing Bitcoin’s consensus rules so that 79,956 BTC — currently sitting untouched in a single wallet — could be moved to a designated recovery address without access to the original private key. At today’s prices, those coins are worth more than $5.2 billion.
Coins Frozen for 15 Years
“These coins have not moved in over 15 years,” Karpelès noted, describing them as some of the most closely watched dormant Bitcoin in existence.
He acknowledged that the proposal would require a hard fork — a major network upgrade that would make previously invalid transactions valid. For it to work, node operators would need to update their software before a specified activation block.
Karpelès insists the idea isn’t an attempt to bypass Bitcoin’s development process. Instead, he says it’s meant to break a long-standing stalemate.
According to him, bankruptcy trustee Nobuaki Kobayashi has avoided pursuing an on-chain recovery because there’s no guarantee the Bitcoin community would support such a move.
“That creates a deadlock,” Karpelès wrote. “The trustee won’t act without confidence, and the community can’t evaluate the idea without a concrete proposal.”
If recovered, the Bitcoin could be distributed to creditors through the existing bankruptcy process. Many former users of Mt. Gox are already receiving partial repayments more than a decade after the exchange collapsed.
Backlash From the Bitcoin Community
The proposal quickly sparked strong reactions across Bitcoin forums. Critics argue that rewriting Bitcoin’s rules to recover stolen funds — even in a case as significant as Mt. Gox — would undermine one of Bitcoin’s core principles: immutability.
Some users warned that if the network makes exceptions once, it could open the door to future demands every time a major hack occurs. Others stressed that Bitcoin should remain independent from court rulings or legal decisions in any jurisdiction.
Karpelès, however, maintains that the Mt. Gox case is different. He argues that both law enforcement and much of the crypto community agree the wallet in question contains stolen funds from the exchange’s 2014 collapse.
Several individuals claiming creditor status voiced support for the idea, saying any additional recovery would help offset the massive losses they suffered.
A Collapse That Shaped Crypto History
At its peak between 2010 and 2014, Mt. Gox handled roughly 70% of global Bitcoin trading. But behind the scenes, a massive theft had gone undetected for years. By the time the exchange filed for bankruptcy in Tokyo, around 750,000 customer Bitcoin had disappeared.
More than a decade later, the fallout from the collapse still lingers, making it one of the largest and most defining failures in crypto history.
In a related development, investment firm Strive — co-founded by Vivek Ramaswamy — announced last year that it plans to acquire 75,000 Bitcoin, worth just over $8 billion, through claims linked to the Mt. Gox bankruptcy estate.
