🔐 Coldcard Wallet Flaw Linked to $100M in Bitcoin Losses

A vulnerability in Coldcard hardware wallets has been tied to losses exceeding $100 million in Bitcoin, reigniting debate over entropy quality in key generation and the reliability of dice-based randomness.

The exploit centers on how private keys are generated. Insufficient entropy — the randomness required to produce a secure key — can result in keys that are predictable and therefore vulnerable to brute-force attacks. The incident has raised scrutiny over whether Coldcard's key generation process adequately mixed user-supplied dice rolls with device-generated randomness, or whether one source could undermine the other.

The case highlights a longstanding tension in hardware wallet design: users who manually input dice rolls to generate keys may believe they are adding security, while a flawed implementation could negate that assumption entirely.

🔐 Coldcard Losses Near $89M as Bitcoin Slides Under $63K

Bitcoin fell below $63,000 despite easing macro pressures, as fresh Coldcard-linked wallet sweeps weighed on sentiment alongside ETF outflows and policy delays.

Oil and Treasury yields declined following U.S.-Iran talks, reducing near-term inflation fears — yet neither Bitcoin nor Ether caught a bid. Observed losses tied to Coldcard-linked sweeps reached nearly $89 million, adding a security overhang to already cautious market conditions.
