Mark Karpelès, former CEO of Mt. Gox, has proposed a Bitcoin hard fork to recover about 79,956 BTC tied to the exchange's 2011 breach, valued near $5.2 billion at current prices, Odaily Planet Daily reports. The plan targets a wallet linked to the hack that received nearly 80,000 BTC and has remained untouched for over 15 years; under current Bitcoin rules only the private key holder can move the coins, and the proposal would allow unspent outputs at a Mt. Gox recovery address to be controlled by signatures from that address so the funds enter the existing court-supervised creditor distribution. Karpelès described it as a discussion starting point with changes limited to a single address and activation at a specified future block height, noting it requires a coordinated network upgrade and that lack of support could risk chain fragmentation; the roughly 80,000 BTC are not currently available for distribution and are not controlled by the bankruptcy trustee.

MARA Holdings (MARA) reported a fourth-quarter 2025 net loss of $1.71 billion, or $4.52 per diluted share, reversing net income of $528.3 million in the year-ago period, according to a shareholder letter filed with the US Securities and Exchange Commission. Revenue fell 6% to $202.3 million from $214.4 million, pressured by a $1.5 billion negative change in the fair value of digital assets tied to Bitcoin's decline from around $114,300 on Sept. 30 to $88,800 on Dec. 31, CoinGecko data show. The company mined 2,011 BTC in Q4 2025, down from 2,144 BTC in the prior quarter and 2,492 BTC in the year-earlier period, and ended 2025 holding 53,822 BTC, including 15,315 BTC loaned or used as collateral, valued at about $4.7 billion based on a quarter-end spot price of $87,498 per coin. For full-year 2025, MARA posted a net loss of $1.31 billion versus net income of $541 million in 2024 while revenue rose to $907.1 million from $656.4 million, and outlined a transition toward energy and digital infrastructure via a joint venture with Starwood Digital Ventures targeting over 1 gigawatt in its first phase alongside a February acquisition of a 64% stake in Exaion.

Former Mt. Gox CEO Mark Karpelès proposed a Bitcoin hard fork to recover roughly 79,956 BTC, worth more than $5.2 billion at current prices, according to a proposal he published. The plan targets a long-dormant address linked to the exchange's 2011 hack. The coins have not moved in more than 15 years, which the proposal says may indicate the attacker lost keys or chose not to return the funds.

Citigroup plans to integrate Bitcoin custody into its core banking infrastructure by late 2026, extending the bank's existing framework that oversees approximately $30 trillion in assets under management, Citi executive Nisha Surendran said at an industry event hosted by Bitcoin treasury firm Strategy. The initiative will allow institutional clients such as pension funds, insurers and asset managers to hold Bitcoin alongside stocks, bonds and other regulated instruments within Citi's systems. Citi's Integrated Digital Assets Platform is being built to support 24/7 operations, Swift messaging, API connectivity, key management, wallet systems, tax reporting, regulatory compliance tools and risk controls for Bitcoin positions, with initial delivery focused on core custody and later phases adding features like asset segregation and collateral management. Citi is also considering partnerships with specialized firms as the platform evolves, positioning the bank among major US institutions offering digital asset custody while aiming to make Bitcoin function as a standard financial asset inside its existing operational and compliance structure.
