The fundamental security of Bitcoin self-custody depends entirely on proper implementation of cryptographic processes, and flawed random-number generation can compromise even offline storage solutions
Too little corroboration in the last 3 days to call a trend (3 articles). Watching for it to gain traction.
"People who had done everything right, took their BTC off of the exchange, put it into an air-gapped Coldcard powered by a 9V-battery and thought they were safe, found their life-savings irrevocably drained away in an instant. This has enormous implications, not just for Coinkite, the Canadian company who manufactures the Coldcard, but for the entire worldview of self-custody and perhaps even for Bitcoin itself."
"Despite its potential upside, I never bought much Bitcoin because security & key management always freaked me out. According to the German blockchain developer, even perfectly generated private keys are not immune to storage risks, software flaws, or even future tech advances."
"It's a reminder that self-custody is only as strong as the processes used to generate and protect private keys. The device is just responsible for generating your passwords, and if the underlying math is broken then your passwords can be reverse-engineered."
