I know that Electrum is one of the coolest bitcoin wallet out there but I want to be sure of one thing about keeping wallet safe and secured, it's possible to open a new bitcoin wallet using Electrum after installation without online access, I tried this and it worked, my question is if one want to keep the wallet offline this way is it possible?
Before you download and install the Electrum, make sure you have reinstall the device OS. I mean you should make sure you format the device.
Like after having your recovery seed and wallet address you remove the wallet while it's offline, no internet connection and whenever you move funds into the wallet you use explorer to check balance, doing this, does it mean it's truly offline?
It is still a paper wallet. You can use a watch-only wallet with it.
