Users should always have at least two digital wallets (or even more, depends on amount of crypto funds). One wallet should be used for trading and transactional purposes, and the other wallet should be used to store savings and be kept in a secure location. This type of wallet must be a cold storage wallet. In anyway, a backup of the private keys have to be stored safely offline (it’s a good idea to separate the private key into 2-3 parts and store them safely away from each other).
