Wallets are usually stored digitally, either locally or online, but there are more secure ways to store bitcoins. Your bitcoin "wallets" can be printed out and stored on paper. A paper wallet is a slip of paper with both your private and public keys printed on it.
I agree with you the important security of the wallet if the identity is no problem for me, so in my opinion, security must be more favored and must be developed with a qualified feature so that it cannot be stolen and broken down by criminals
