A cryptocurrency wallet is a tool that allows you to store, manage, and transact with your cryptocurrencies, such as Bitcoin and Ethereum. There are different types of wallets, including software wallets (downloadable on devices like phones or computers) and hardware wallets (physical devices). To check your wallet balance, you need to access your wallet's interface and verify the available balance, often displaying the value in different cryptocurrencies and fiat currencies.
