Recently I came across this tutorial:
https://www.youtube.com/watch?v=QgQ8e0WMyUYIt's in Portuguese, but it's basically teaching how to use Bitaddress.org to create a paper wallet and it talks about security.
So far, so good, but it tells you to disconnect from the internet right away after the page is loaded, then generate the whole thing, then here comes the part that I'm in doubt:
The dude says that after generating and printing the thing, that we should restart the computer, but it's better if we format the whole machine. I don't want to have the trouble to format a whole windows machine every time I create a paper wallet, so I had the idea of using a raspberry instead. Since it runs on a SD card, it would be pretty easy to format the card after creating the wallet. Cool, but then I came accross odroid-c2, which is much faster than raspberry PI3 and already comes with eMMC and android. So I'm almost opting for buying the odroid.
In odroid I'm going to use the sd card to run a different Operational System, this way I can follow the whole procedure, question is:
Will I have to format the device's eMMC too?
I mean, I won't save anything internal memory, but I know, I'm afraid I might have trouble.
