What is Centralized Exchange (CEX)?

The centralized exchange serves as one of the most effective means of transaction for most investors in digital currencies. Online marketplaces are centralized cryptocurrency exchanges to allow users to purchase and trade cryptocurrencies. Users most frequently utilize them to buy and sell their cryptocurrency holdings. The idea of a “centralized” exchange may confuse some investors because digital currencies are “decentralized.” Why are these exchanges so crucial for the development of the cryptocurrency sector? Also, what does it imply for an exchange of this type to be “centralized”?

Centralized exchanges (CEXs) coordinate bitcoin trading on a big scale employing financial modeling of operation, which is similar to that of various asset exchanges like securities exchanges.

However, markets are what exchanges are. They are helpful when numerous people might be seeking to purchase and sell the same kind of asset simultaneously. The New York Stock Exchange and the London Metal Exchange are well-known exchanges in the traditional economy. Binance, Coinbase, Gemini, and Kraken are well-known CEXs in the cryptocurrency industry.

What is Centralized Exchange?

The most popular approach to begin trading cryptocurrencies and other technology infrastructure is through crypto exchanges. Private platforms known as cryptocurrency exchanges enable the trade of bitcoins for other crypto assets, such as digital and fiat money and NFTs.

Centralized cryptocurrency exchanges serve as a middleman between buyers and sellers and generate revenue through royalties and credit card fees. You may think of a CEX as a stock exchange for digital assets. Binance, Coinbase Exchange, Kraken, and KuCoin are well-known cryptocurrency exchanges. These exchanges let cryptocurrency investors buy and sell digital assets at the current price, known as spot, or leave contracts completed when the asset reaches the investor’s preferred price objective, known as limit orders, like stock trading websites or applications.

The buy and sell transactions are documented and arranged by the anticipated buy or sell price in the order book system used by CEXs. So using the highest feasible price given the required lot size, the exchange’s matching engine subsequently pairs buyers and sellers. Therefore, the price of a digital asset, whether in the form of fiat money or cryptocurrency, will depend on the quantity and demand of that asset relative to other assets. It is up to CEXs to decide which digital products they will permit trade-in, which offers some reassurance that might bar dishonest digital assets from the CEX.

  • A cryptocurrency exchange is the most popular platform for trading cryptocurrencies and other digital assets.
  • Each type of cryptocurrency exchange, centralized and decentralized, has benefits and drawbacks.

How CEX Works?

An exchange for cryptocurrencies serves three primary purposes:

Matching Orders

Buyers and sellers trade money on a cryptocurrency market. So this indicates that you purchase cryptocurrency from another exchange user instead of the exchange itself. People who wish to buy cryptocurrency can do so on the exchange, and those who would like to sell their cryptocurrency, including matching Buyers and vendors. For example, the exchange will check the contracts of these two parties if a buyer wants to purchase bitcoin (BTC) for $20,000 and a seller wishes to offer bitcoin for the same amount.

Getting Counterparty Clear

Also, serving as a central clearing opponent is the exchange. It simply means that all completed orders appear to direct at the exchange AS A WHOLE rather than between specific users. Since neither the buyer nor the seller will be aware of the other’s identity, this preserves both sides’ anonymity. Additionally, the CEX manages the entire transaction process and ensures that t fulfills all obligations between the buyer and seller and that the transaction closes as the central clearing counterparty.

For instance, if you paid $1000 for one bitcoin (BTC), the exchange will ensure you have $1000 (USD), transfer the USD to the seller’s account, and then send the freshly acquired BTC to your account. You cannot simply take the bitcoin and vanish; the vendor cannot merely take your dollars and vanish. 


Additionally, the exchange is a custodian for any money or cryptocurrency held in your account. You can deposit fiat money like dollars or euros on some exchanges, but only cryptocurrencies like bitcoin (BTC) or ether accept by others (ETH). Once transferred, they are in the exchange’s care, whether in fiat or cryptocurrency. So this means that you are now putting your confidence in the exchange in the same manner that you would put your trust in a safety deposit box to hold your money. 

Decentralized Cryptocurrency Exchanges

Another sort of exchange that enables peer-to-peer transactions straight from your digital wallet without using an intermediary is a decentralized exchange. Uniswap, PancakeSwap, dYdX, and Kyber are a few DEXs. Blockchain-based smart contracts, self-executing code bits, power these decentralized exchanges. Compared to a centralized bitcoin exchange, these smart contracts provide better privacy and less leakage (another term for transaction fees). However, even though documents contain regulations, the lack of a middleman leaves the user alone, making DEXs appropriate only for experienced investors.

Difference between Centralized and Decentralized Exchanges

However, they can make trades between fiat currency and cryptocurrencies on centralized exchanges (or vice versa). In addition, somebody can use them to carry out transactions involving two different cryptocurrencies. Although this might cover all possible transaction kinds, there is still a demand for a different bitcoin exchange. Decentralized exchanges provide an alternative; eliminating the middleman creates a “trustless system.” Mentoring exchanges are what these kinds of trades do. Escrow services never hold assets; all transactions use blockchain networks and quick swaps. The main distinction between centralized and decentralized exchanges is the presence or absence of a middleman. Compared to centralized exchanges, decentralized exchanges are less common and less well-liked. Nevertheless, cryptocurrency exchanges are growing, and it’s feasible that they will eventually outperform controlled exchanges.

Fiat Pairs Cryptocurrency

A centralized exchange now offers cryptocurrency-to-cryptocurrency matching more frequently than not. Customers could trade bitcoin for ether tokens, for example, thanks to this. Fewer exchanges provide fiat currency/cryptocurrency pairs, making it possible to swap bitcoin for USD. These fiat/crypto pairs provide some of the world’s biggest cryptocurrency exchanges. They probably act as a direct entry point to the bitcoin market, which is part of this explanation.

Investors may use these kinds of exchanges more frequently because many are still learning to invest in digital currency. These platforms include Gemini, Coinbase, Robinhood, and Coinbase.

Advantages of Centralized Exchange

  1. Convenient

Centralized exchanges provide newcomers with a comfortable, familiar approach to trade and investing in cryptocurrencies. Users of centralized exchanges may log into their accounts, examine their general ledger, and transact business through apps and sites rather than peer-to-peer transfers and crypto wallets, which can be complicated.

  1. Dependable

Centralized exchanges provide higher security and dependability for transactions and trading. In addition, centralized exchanges offer greater comfort by simplifying purchases through a developed, centralized platform.

  1. Employ

The ability to leverage your purchases using external financial budgeting from the exchange, known as margin trading, is one of the other advantages of some CEXs. Higher gains are possible for investors, but somebody may also exaggerate losses.

Disadvantages of Centralized Exchange

  1. Risk of hacking

Organizations that are accountable for their clients’ holdings run centralized exchanges. Multiple vendors frequently hold bitcoin valued at billions of dollars, making them a vulnerability to theft and hackers. Mt.Gox, formerly the biggest cryptocurrency exchange company in the world before it announced the theft of 850,000 bitcoins and caused its demise, is an example of such an instance.

  1. High Transaction Costs in Centralized Exchange

For their products and accessibility, centralized exchanges frequently demand hefty transaction fees, which can be particularly exorbitant when trading in significant sums, in contrast to peer-to-peer transactions.

  1. Digital Asset Ownership and Fraud Risk

Most CEXs won’t let you save your private keys on your digital wallet; instead, they will maintain your digital asset as a custodian inside their digital wallet. So this is the most crucial point. There are disadvantages, like the possibility of the centralized cryptocurrency exchange malfunctioning and fraud, even though it is more practical when you want to trade.

Examples from the recent past include the failure of the 50 billion USD computational stablecoin TerraUSD and sister token Luna, the insolvencies of the hedge fund Three Directions Capital, the lender’s Celsius System and Voyager Digital, and the brokers FTX and Alameda Research.

Primary Elements of Centralized Exchange

People constantly launch centralized cryptocurrency exchanges. However, not each of them will be profitable, and these exchanges frequently fail. A firm’s success or failure depends on a variety of variables. Trading volume is one of the essential ingredients for success, though.

Generally speaking, the lesser the volatility and likelihood of market manipulation on a particular exchange, the higher the levels of trade volume. However, volatility is an essential factor. For example, the price of a specific token or coin can increase after a short time it is started, and the time it is concluded since transactions take time to complete. The likelihood that this fluctuation will cause a problem decreases with increased trade volume and transaction processing speed.

Security is yet another essential component of an excellent centralized exchange. All exchanges are susceptible to harmful activities, like hacks. However, some are more secure than others. It’s certainly not how an exchange will respond to a cyberattack. While some exchanges have made a significant effort to compensate customers for their losses, others have had less success. These kinds of attacks have caused the closure of even other businesses.

The most popular way for investors to get started in the bitcoin field is still through a centralized exchange. Therefore, it’s crucial to consider various elements when choosing an exchange, such as the currency pairs offered, the volume of trades, and the encryption methods that exchanges have implemented to safeguard their users.
