Know Your Customer (KYC) is a process used by financial institutions, including CEXs, to verify the identity of their users.
It involves collecting personal information and documentation. KYC helps prevent illegal activities like money laundering and fraud.
Most reputable CEXs require KYC verification to comply with regulatory requirements, meaning trading anonymously is generally impossible on these platforms.
If a CEX goes bankrupt or shuts down, users may lose access to their funds. Some exchanges may have insurance or recovery plans, but they are not guaranteed.
This is why keeping necessary funds in exchange and withdrawing excess funds to a personal wallet is crucial.
Trading pairs on a CEX refer to the two different cryptocurrencies that can be traded against each other.
For example, BTC/USDT is a trading pair where Bitcoin can be traded for Tether.

An order book is a real-time list of buy and sell orders for a specific trading pair on an exchange.
It shows the prices and quantities of assets traders are willing to buy or sell.
