For the best security, you need cold storage. Cold storage on the blockchain world means devices that are disconnected from the Internet. This is the hardest possible security measure to protect the crypto investment from the interests of hackers.

Even if your wallet falls into the wrong hands, a cold storage solution offers advanced encryption to prevent even the most severe hacking. There are several cold storage solutions available on the market today. They are also referred to as hardware wallets like Ledger Nano S and Trezor.
