Coldcard's Bitcoin-only hardware wallet is facing scrutiny after an entropy vulnerability was exposed in private key generation. The issue stems from insufficient randomness during seed creation, which has raised questions about how this affects security in BTC wallets built since 2017.

The problem was first detailed by Decrypt, highlighting the potential risks associated with using Coldcard for Bitcoin transactions.

Bitcoin is currently trading at $64,326.47 within Bollinger Bands, with an upper resistance level of $64,429.88. The MACD golden cross at 114.22 reinforces the bullish trend above EMA50 support at $63,751.94, while the RSI holds neutral at 59.53.
