I don't have the luxury of hardware wallets or paper wallets, anything more complicated than an offline wallet. I'm a simple man, using the Electrum wallet. Your safest bet would be to type your seed phrase on a small piece of paper and tape on the bottom side of a drawer. Create one or two copies and recreate the same hiding pattern, and you'll be good to go.
What do you say storing the seed phrase on bank safety deposit box?
