A low-entropy vulnerability in the Coldcard hardware wallet has prompted bitcoin users to recheck how they generate seed phrases. Community focus has shifted toward physical entropy methods such as rolling dice rather than relying on device-based random number generators. After July 30, theft cases were publicly confirmed, with attackers brute-forcing private keys and stealing more than $100 million in BTC. Users are revisiting “don’t trust, verify” and exploring multiple offline methods to generate and cross-check BIP-39 seeds.

A security warning has been raised over how Dogecoin is stored, with a community contributor cautioning that creating a wallet on a computer disconnected from the internet does not guarantee safety. Mishaboar said malware or compromised hardware and operating systems can capture seed phrases and later exfiltrate them when the device reconnects. He said keeping assets on exchanges is not a fundamental solution and urged users to diversify wallets, use passphrases and keep offline backups.
