A crypto wallet helps you buy, sell, and store your cryptocurrency and (in many cases) your NFTs.

In simple terms, a crypto wallet helps you buy, sell, and store your cryptocurrency and (in many cases) your NFTs. Going a level deeper, a crypto wallet manages access to your private key, which is needed to control a blockchain wallet address. Your cryptocurrency and NFTs are not stored in/on a crypto wallet; they remain on the blockchain and can be accessed, controlled, and managed through use of a crypto wallet. Think of your wallet as the key to your address on the blockchain — you use the key to open the safe where your items are stored on the blockchain and use the key to send/receive items to/from your address on the blockchain. Just like any key, security of your wallet and private key (or seed phrase) are critically important.
