What is the difference between a cryptocurrency wallet and an exchange?

A cryptocurrency wallet is a secure digital wallet used to store, send, and receive digital currency. It is similar to a traditional wallet, but instead of storing physical currency, it stores digital information such as private keys, public keys, and addresses, which are used to access and transfer cryptocurrency.

On the other hand, a cryptocurrency exchange is an online platform where users can buy, sell, and trade cryptocurrencies. Exchanges offer a variety of services such as trading, margin trading, and derivatives trading, and allow users to exchange different types of digital currencies.
