A crypto wallet is a digital tool that allows users to store, send, and receive cryptocurrencies like Bitcoin and Ethereum. Unlike a traditional wallet that holds physical cash, a crypto wallet stores the private and public keys needed to access and manage your digital assets. There are two main types of crypto wallets: hot wallets, which are connected to the internet for easy access, and cold wallets, which are offline for enhanced security. Each type has its advantages and disadvantages, depending on how frequently you plan to use your cryptocurrencies and your security needs.
