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?
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?
You have to do it with following steps.
Download Electrum wallet.
Verify its signature.
Turn off Internet connection.
Create your wallet offline.
Backup your wallet seed phrase.
Delete that wallet file on your computer.
But using Block explorers to check your transaction history, wallet balance is not recommended. It is not good for your privacy because block explorers can be owned by third parties and can use data when you check your wallet on the explorer to track you. They can even sell data to other guys then data breach start to spread more.
