I know this has been probably asked a million times but I decided to go all in (investment money speaking) on bitcoin so I am looking for a safe wallet.
I have some stored in blockchain digital wallet but want to take it offline just in case. I did use electrum in the past and still considering it.
You already had the offline wallet that I'm about to suggest, electrum is what almost everyone prefer here. And I have some funds there probably 1 bitcoin and I don't have any plans on using them that's why you are good to go with electrum and there's no need to worry about it because it's one of the safest offline/desktop wallet ever.
I am also using electrum and I have no issue using it. I used to save my bitcoin in Multibit but the moment they upgraded to HD, they remove our rights to save private keys (probably there is still option to but I cannot find it) I think these wallets are safe as long as your system is not compromised. Others also use paperwallets.
Yes, electrum is the one that gives the best access and make it an secure way for saving bitcoin. Personally most of the users prefer Blockchain.info which has gained the trust than other wallet under the online wallet segment.
