Use Your Old Phone To Store Bitcoin?
From Matthew Kratter's Bitcoin University
Video Description
> 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. Even the touchscreen hardware and software could leak your keys.
