A cryptocurrency exchange is an online platform built on blockchain technology. Before starting to trade, we need to log in to the cryptocurrency exchange. First, we need to go to the official page of the cryptocurrency exchange and click on the login button. Then provide personal details like name, email id, mobile number and verify it. We need to provide id proof for KYC verification. Once we complete the KYC verification, we can start our crypto trading.

Mark is a crypto trader and he wants to buy 1 BTC for $45,000. He needs to place a buy order with the quantity and price. This buy order gets stored in the order book.
Dieter is another crypto trader and he wants to sell 1 BTC that he holds for the same price as Mark. He places a sell order with the quantity and price amount. This sell order will get stored in the order book.
The match engine matches the buy and sell order and completes the trade.

Apart from trading, exchanges provide many services like staking, lending, margin trading, P2P trading, and more.
