A crypto wallet is a secure place where you store your crypto funds. Wallets are created using private and public keys.
With access to a crypto wallet, you can check your crypto balance and transaction history and move funds around the world using the blockchain. Funds stored in crypto wallets are protected from being stolen physically. However, every owner of a crypto wallet should care about its security, which includes keeping your password safe, enabling two-factor authentication if possible, and taking other measures.
There are several types of wallets you can use including online wallets, cold wallets, mobile wallets, hardware wallets, and desktop wallets. They vary in the way you can access them (over the internet or locally on your device) and their level of security.
