Join the Saturday live class:https://www.bitcoinuniversity.com/joinIn this video, I discuss why it's a terrible idea to try to repurpose your old phone as a Bitcoin hardware wallet.Bitcoin hardware wallets are devices where the hardware and software has been stripped down as much as possible, in order to narrow the attack surface.By contrast, devices like phones and computers with their many chips, operating system software, other software, apps, and possibly malware and backdoors are a really terrible place to store your seed.
