What is a Bitcoin exchange?

A Bitcoin exchange is fundamentally a marketplace where users can buy, sell, or swap Bitcoin as well as other cryptocurrencies. These platforms facilitate trading by allowing users to create accounts and use various payment methods to transact. They provide a user-friendly interface and a mechanism to match buyers with sellers, which enables liquidity in the cryptocurrency market.

In this context, Bitcoin exchanges also serve as critical infrastructure for the cryptocurrency ecosystem, often providing features such as real-time price tracking, trading charts, and tools for analyzing market trends. By centralizing the trading process, exchanges help establish market prices for Bitcoin and facilitate liquidity, enabling individuals and institutions to easily enter and exit positions.

Other options describe different concepts related to cryptocurrency but do not accurately capture the function of an exchange. Mining is the process of validating and adding transactions to the blockchain, while a blockchain project using Bitcoin transactions refers to specific applications or functionalities built on the Bitcoin network. A wallet, on the other hand, is a tool used to store, send, and receive cryptocurrencies, rather than a platform for trading them.
