It was founded in 2017 by Changpeng Zhao and has quickly risen to prominence due to its user-friendly interface, extensive coin listings, and various features like spot trading, futures trading, staking, and more.

The crypto world, in general, refers to the ecosystem of digital currencies, blockchain technology, decentralized finance (DeFi), non-fungible tokens (NFTs), and other related innovations. It's a rapidly evolving space with a lot of potential for disruption across various industries, including finance, technology, supply chain management, and more.
