cryptocurrency wallets
Blockchain key storage
Cryptocurrency wallets are software or hardware tools that store the cryptographic keys needed to access and manage digital currencies like Bitcoin.
Despite the name, they don't hold currency itself—they hold the private keys that prove ownership of assets recorded on a blockchain.
Hot wallets connect to the internet for convenience; cold wallets stay offline for security.
I keep most of my Bitcoin in a hardware wallet.
