Binance Founder CZ Urges Wallet Diversification After $70M Coldcard Hack
Changpeng Zhao warned crypto holders to spread assets across multiple wallets following a $70 million exploit targeting Coldcard hardware wallets.
Binance founder Changpeng Zhao, widely known as CZ, publicly urged cryptocurrency holders to diversify their wallet storage after a $70 million exploit struck Coldcard, a prominent hardware wallet provider, according to a CoinDesk report. The call to action came as details of the breach rattled confidence in hardware-based cold storage solutions long considered among the most secure options available to crypto investors.
CZ took to social media to warn users against concentrating their digital assets in any single wallet or storage solution, arguing that spreading holdings across multiple platforms and devices reduces exposure to catastrophic loss in the event of a single point of failure. His message resonated loudly given the scale of the Coldcard incident, which ranks among the more significant hardware wallet compromises in recent memory.

The exploit highlights a growing reality in the digital asset space: even solutions marketed as offline and air-gapped are not immune to sophisticated attack vectors.

Security analysts have long advised a layered approach to crypto custody — combining hardware wallets, multi-signature schemes, and geographically distributed backups — but such practices remain underutilized among everyday holders. CZ's high-profile endorsement of diversification may push more users toward adopting that discipline, particularly at a moment when on-chain asset values remain elevated and the incentive for bad actors is correspondingly high.
The incident serves as a stark reminder that no single custody method is foolproof, and that the responsibility for safeguarding digital wealth ultimately rests with the individual holder. Continue reading at CoinDesk.
