Crypto exchanges are the platforms that facilitate the exchange of cryptocurrencies for fiat money or other digital assets. You can learn more about crypto exchanges in our detailed guide
To put it simply, the crypto exchanges connect crypto sellers and buyers and work like a stock exchange.
The crypto exchanges are either centralized (CEXs) or decentralized (DEXs). Both have their advantages and disadvantages.
The CEXs are controlled by a single entity, like a company; on the other hand, decentralized systems have distributed control similar to blockchain technology. Coinbase, Kraken, KuCoin, and OKX are some of the famous centralized exchanges. Dolomite and Serum are examples of decentralized exchanges.
Here is a detailed comparison between CEXs and DEXs to help you decide which is best for you.
Decentralized Exchanges (DEXs) Vs Centralized Exchanges (CEXs)

In the case of centralized exchanges, you need to entrust the funds to the exchange. The custody of your digital assets and managing the private keys are done by the exchange itself.
As for decentralized exchanges, you are in complete control of your digital assets.
2. Ease of Use
The centralized exchanges have higher user friendliness and customer support. Hence, they are more appealing to beginners.
For decentralized exchanges, you need a digital wallet and an understanding of concepts like gas fees. The gas fee is the transaction fee incurred to process transactions or run smart contracts on a blockchain network.

Due to the increased user friendliness of centralized systems, they are easier to adapt. The decentralized systems required special knowledge to operate, hence less popular among crypto traders.
Despite a lower historical adoption rate, the popularity of DEXs is increasing as the technology backing it is evolving faster.
9. Speed
The Centralized exchanges have higher transaction speed as it is centrally controlled. In decentralized exchanges, the transaction speed is variable depending on the blockchain network.
