Recently, I saw an article about cold wallet in coingeko, talking about cold wallets, I then remembered a friend of mine back in 2022, that was hitting it big back then in the crypto space, he bought 2 cold wallets and decided to store it there, I asked why, he said for security, he went on to explain how it works, it's basically like a storage device/memory card although it's shaped as a USB drive, you store your crypto data in there.
It is not every cold wallet that has the shape of a USD drive, and the security of the crypto your friend has in the wallet is determined by how s/he use the wallet.
No matter how secure the cold wallet is, if your friend uses it in the way that will expose the wallet to vulnerability s/he will still loose the crypto in the cold wallet.
I was like is this truly secured, what if u lost it and this can literally be stolen, he said it was password protected and it do have recovery phrase, tha blew my mind, it's like holding your crypto in your hand literally.
Yes, every self custody wallet has a password, backup seed phrase, and privacy keys, which can be used to recover all the crypto in the wallet. However, you still need to keep them in at least two secure locations.
