Paper wallets are pretty weak, let's be honest. If someone were to offer you a superior way to keep Bitcoin in offline (PHYSICAL) form, would that interest you?
Brutally honest? Ok.
How is paper not physical?
And let me add to that:
How are they weak?
If you create a paper wallet on an offline computer, then completely erase all data from that computer (hell, even get a cheap old pc and destroy it afterwards),
how is that weak?
Please enlighten me.
