Some things are not still clear.
How can I create a offline wallet if the PC with the offline wallet will not be ever connected to the internet?
So, to create a "offline" (?) wallet I take this Netbook or Raspberry PI 3, connect to internet once, create an 2Factor Authentication wallet Bitcoin, backup seeds on a paper, exporte private keys on a safe crypted USB (right, or I don't need to backup exported private keys?), then I send Bitcoins from Blockchain. info to Electrum address, then I'm 100% sure?
I still don't understand how can be offline if I create it online, this concept is not clear, I mean, the Bitcoin are saved on the PC itself, so can't be stolen if I'm cautious? I can connect it to the internet btw once in a while, I'm safe here, but I wanna be 100% sure that Electrum and other sites do not own my bitcoins like online wallet do
And I only need seeds, not private keys?
For example, if I lose everything to access my wallet, keys (still don't know if I have to backup and don't know how they work
), PC, Google Authenticator, literally everything except for the 12 words, and 10 years after I decide to restore my wallet with the 12 words, can I do that, right? I mean, so, I only need those 12 words and I'm 100% safe that I can restore my bitcoin in future or immediately
