Corporate Bitcoin holders are confronting significant governance and security gaps as recent incidents highlight the risks of inadequate custody controls. The Coinbase breach, in which criminals bribed support staff to steal customer data including names, addresses, and balances, is estimated to cost up to $400 million. Security researchers warn that such data exposure increases the risk of real-world coercion against asset holders. The threat landscape is compounded by physical attacks on Bitcoin owners, with over 360 known incidents logged since 2014, including more than 60 cases recorded so far in 2026. Historical failures like QuadrigaCX’s loss of $190 million after its CEO died holding sole key access, and Prime Trust’s inability to access legacy wallets for years, underscore the critical need for robust operational protocols. Boardrooms are increasingly scrutinizing who can move assets, who approves transactions, and what happens when credential holders leave or are compromised. A Deloitte survey of 200 CFOs at billion-dollar companies revealed that accounting and control complexity was a barrier for 42% of respondents, nearly matching price volatility concerns. These structural weaknesses have caused many firms to abandon plans to hold Bitcoin on their balance sheets.
