Please review my steps:
0) download a linux distro (me its mint 17) and electrum
1)) create a bootable usb key of linux mint
2) put electrum in another usb key
3) turn off computer
4) turn off wifi
5) boot into linux mint
6) verify you dont have an internet connection
7) install electrum via usb key
create a new wallet and memorize the seed and then write it on a piece of paper
9) copy your master public key into a usb key
What do I do next ? I have trouble understanding what a master public key is!
Should I save one of the address and then launch my online pc and send bitcoin to this address?
