Coldcard Vulnerability Has Resulted in Nearly $114 Million in Bitcoin Losses, With Insufficient Entropy in Some Wallet Mnemonics
Odaily Planet Daily Report: Bitcoin hardware wallet manufacturer Coinkite disclosed in late July 2026 that a firmware build error introduced in March 2021 caused some Coldcard wallets to generate mnemonics from a smaller range, reducing the randomness of user private keys.
Galaxy Research analysts stated that the Coldcard exploit occurred in multiple rounds, with observed Bitcoin losses rising from approximately $88 million to nearly $114 million within days. Researchers warned that other vulnerable addresses could still become targets, prompting many Coldcard users to move their Bitcoin.
Coldcard is a Bitcoin-only wallet that supports offline signing via microSD card and optional QR codes. Launched in 2017, it has long been regarded as one of the security-focused Bitcoin hardware wallets.

Permissions opened: MARA Slipstream becomes a permissionless public service with no client software required
Odaily Planet Daily News Bitcoin News posted on X platform, stating that MARA's Slipstream is now open as a permissionless public service, requiring no client software. This service is particularly important for users transferring funds from vulnerable COLDCARD wallets. Multi-signature spending exposes all public keys and spending conditions. If this transaction enters the public mempool, attackers can immediately match these keys against their pre-computed database of weak COLDCARD private keys, and if they control the majority of keys, broadcast a higher-fee double-spend transaction before the original transaction is confirmed. Slipstream submits transactions directly to miners, keeping them out of the public mempool until mined. MARA recommends using conservative fees to avoid transactions getting stuck. Aside from standard Bitcoin network fees, the service is currently free.

Michael Saylor Reaffirms No Bitcoin Sold: Strategy Is a Public Company, Its BTC Buys and Sales Are Unrelated to Personal Holdings
Odaily News, Michael Saylor stated that he has never sold any Bitcoin and reaffirmed his position of holding BTC for the long term. Saylor said on social media: "When I say 'never sell your bitcoin,' I say it as a saver to another saver. I have never sold my own bitcoin—not even a single sat."
He emphasized that Strategy is a public company, not his personal wallet. Since 2020, the company has disclosed that it may buy or sell BTC based on capital management needs, but this does not affect his belief in Bitcoin's long-term value.
Saylor said the shared Bitcoin conviction between the company and individual investors "has not changed." Strategy has used Bitcoin as its primary reserve asset since 2020 and remains one of the largest publicly traded companies globally in terms of BTC holdings.
This response addresses recent market discussions regarding adjustments to corporate Bitcoin holdings strategy. Saylor sought to emphasize the distinction between an individual's long-term holding philosophy and a public company's asset management based on financial needs.
