The largest crypto exchange in the world by volume. They've committed a huge amount of crimes and a large part of the crypto community wants CZ in prison for a second time. But still, this is where the deepest liquidity is, wide token selection, access in 180+ countries. Spot, futures, margin, staking, launchpad, P2P and an entire DeFi ecosystem. Sometimes the exchange is too big - regulatory problems in several regions. But in terms of trading power, it's unmatched.
