For those who are new to the world of cryptocurrency or prefer a reputable company, a centralized exchange may be the best option. On the other hand, for those who seek to trade lesser-known cryptocurrencies and have full control over their crypto wallet, a decentralized exchange is the only choice.
Centralized Crypto Exchange
A Centralized Crypto Exchange (CEX) is a company that provides a variety of services, including a crypto trading platform, account services, and customer support.
A CEX allows anybody with an internet connection to discover and deal with crypto assets and is appealing to many crypto users since it is more convenient and easier to use than a decentralized exchange (DEX).
It is owned and run by a private company, and participation requires users to join up and create an account. Centralized crypto exchanges allow crypto asset transactions between buyers and sellers by providing an online trading platform with an order book, which is a collection of buy and sell orders submitted by individual traders. UnitEx, Binance, Coinbase, Kraken, and Kucoin are some of the examples of centralized exchanges.
Buyers and sellers conduct business with one another on a cryptocurrency exchange. In other words, rather than purchasing cryptocurrency directly from the exchange, you do it through another user.
The exchange itself offers a location for those looking to acquire cryptocurrency and those who want to sell their existing cryptocurrency. It connects purchasers and vendors. When a buyer wants to purchase a cryptocurrency at a specific price and a seller wants to sell the same cryptocurrency at the same price, the exchange will match their orders.
The exchange serves as a central clearing counterparty. That is, all matched orders appear to be against the exchange rather than between the users directly. Because neither the buyer nor the seller knows who the other is, both sides benefit from anonymity.
Furthermore, as the central clearing counterparty, the CEX manages the whole transaction, ensuring that all obligations between buyer and seller are satisfied and the transaction is completed.
The exchange also serves as a custodian for any cash or cryptocurrency in your account. Some exchanges accept fiat currency deposits, while others solely accept cryptocurrencies. Once deposited, cash or cryptocurrency are in the possession of the exchange. This implies you're now relying on the exchange to keep your assets safe in the same way you'd rely on a bank's vault to keep your money safe.
Centralized Crypto Exchanges vs Decentralized Exchange
Centralized exchanges provide a platform for trading between fiat currency and cryptocurrency or between two different cryptocurrencies. While these exchanges cater to a wide range of transaction types, there exists a demand for another type of cryptocurrency exchange.
As an alternative, decentralized exchanges eliminate the presence of a middleman, creating a "trustless" environment for trades. These exchanges operate on a peer-to-peer basis and allow for transactions to be executed through smart contracts and atomic swaps without the need for an escrow service.
The key difference between centralized and decentralized exchanges lies in the existence of a middleman. Currently, centralized exchanges are more widely used and popular, but there has been a rise in the number of decentralized exchanges. It is possible that they may pose a threat to centralized exchanges in the future.
Advantages and Disadvantages of a Centralized Crypto Exchange
Advantages of Centralized Cryptocurrency Exchanges:
- User-friendly interface: Centralized exchanges provide a straightforward and easy-to-use platform for beginner investors to trade and invest in cryptocurrencies. Instead of navigating the complexities of crypto wallets and peer-to-peer (P2P) transactions, users of centralized exchanges can access their accounts, view account balances, and make transactions through websites and applications.
- Reliability: Centralized exchanges provide an extra level of security and reliability when it comes to transactions and trading. The transactions are facilitated through a centralized platform, offering greater peace of mind to investors.
- Leverage: Certain centralized exchanges offer the option of margin trading, where investors can borrow money from the exchange to increase their returns. However, this also amplifies the risk of losses.
Disadvantages of Centralized Cryptocurrency Exchanges:
- Hacking risk: Centralized exchanges are operated by companies that hold their customers' assets. Large exchanges can hold billions of dollars in crypto, making them targets for hackers and theft. For example, Mt.Gox, which was once the largest cryptocurrency exchange, suffered the theft of 850,000 bitcoins, leading to its collapse.
- High transaction fees: Unlike P2P transactions, centralized exchanges often charge high fees for their services and convenience. These fees can be particularly high when trading large amounts.
- Custody of digital assets and risk of fraud: Most centralized exchanges hold digital assets as custodians in their own digital wallets, rather than allowing the customer to store their private keys in their own digital wallet. While this is more convenient for trading, it also introduces the risk of the centralized exchange failing or committing fraud. Examples include the failure of TerraUSD and Luna, the bankruptcies of Three Arrows Capital, Voyager Digital, and the sudden collapse of FTX and Alameda Research.
