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.
Buy some real storage like trezor which is one of the best hardware wallet as of now and there is a lot of serious investors who invested in bitcoin and store it on trezor but the if you want to be more secured then you should divide it into different hardware wallets like buying some ledger hardware wallet so you can have at least two storage for your serious bitcoin investment.
