Cryptocurrency exchange platforms are a great way to start trading cryptocurrency.
As the number of cryptocurrencies on offer continues to grow, most crypto exchanges have grown accustomed to offering users a variety of coins, tokens, or altcoins. These digital assets can be traded for other cryptocurrencies such as Bitcoin and Ethereum.
It can be difficult to choose the right exchange for you, given all of the options available.
How Centralized Crypto Exchanges Work
It is very easy to purchase your cryptocurrency once your money has been deposited on a CeX. The CeX usually comes with a built-in crypto wallet that you can use to store your cryptocurrencies. You can also withdraw your crypto assets to another wallet.

Every centralized exchange features a different internal architecture; however, most centralized exchanges operate with order books that match buy and sell orders.
A CeX's order book lists all orders (buy and sell) from users looking to trade cryptocurrencies on that particular exchange with prices ranging from the best offers, best bid, high, low, etc.
Once an order is matched by a counter-party (i.e., a buyer or seller), the order will be taken by the platform operators, who match the orders and provide liquidity, thus enabling an efficient and fast trade execution at the best price.
How Decentralized Crypto Exchanges Work
Decentralized exchanges are also easy to use; however, there is a learning curve involved. These types of exchanges allow you to buy cryptocurrencies from other users with nothing but the blockchain as the intermediary.
People who wish to exchange cryptocurrency without the need to use a third party or trust a central entity for safety and security are well-suited to DeXs.
There are two categories of decentralized changes: order-book-based decentralized exchanges and automated market-making DeXs.
Decentralized, order-book-based exchanges work in the same manner as centralized exchanges. They list all orders on an online order book and price range from the lowest asking prices to the highest bids. The difference is that they deploy a decentralized framework to match and settle transactions. Automated market-making DeXs don't use order books. They use smart contracts to match and settle orders between a user's wallet and a smart contract. AMM DeXs also outsource liquidity from platform users.
