How Do Cryptocurrency Exchanges Work?

Crypto Exchange

Buyers and sellers can trade crypto assets on a cryptocurrency exchange. If you want to trade crypto, you’ll have to do so through a crypto trading platform because, for the time being, just a few traditional financial organizations provide it.

Crypto exchanges can be classified as centralized, decentralized, and hybrid. Other options for buying and selling crypto include investing apps and P2P (peer-to-peer) networks, which allow you to purchase and sell crypto 1:1.

Learn about the many types of exchanges, how a cryptocurrency exchange interacts with your crypto wallet, and how to choose the right one.

How Does a Cryptocurrency Exchange Work?

A crypto exchange account allows you to purchase and sell cryptocurrencies such as Bitcoin (BTC), Ether (ETH), Polkadot (DOT), Dogecoin (DOGE), and others. Depending on the exchange, you can purchase crypto with a fiat currency like the US dollar or trade one kind of crypto for another.

The longer a service has been around, the more probable it is to provide a variety of cryptocurrencies. Before creating an account, double-check that the cryptocurrency you want is available.

On a crypto exchange, you may buy crypto with conventional fiat money, or you may be able to trade one currency for another. You may be able to convert your cryptocurrency into fiat currency, retain it in your account for future trades, or withdraw it as fiat. The services accessible may vary depending on the exchange or app you use. Some services, for example, don’t allow you to move your cryptocurrency from the platform to your wallet.

Unlike traditional exchanges with set trading hours, cryptocurrency exchanges are active 24 hours a day, seven days a week.

How to Trade on a Crypto Exchange?

Your wallet needs to be replenished. It’s worth noting that wallets provided by an exchange such as CEX.IO are often stored on that platform or app. It’s generally recommended that you set up an external crypto wallet for added security.

The trade prices of various crypto assets can then be viewed. It’s important to note that the market determines the prices, not the exchange. Because cryptocurrencies are decentralized, most exchanges reflect real-time prices, though minor discrepancies may be across them.

You can then place a buy order to buy bitcoin with SEPA at, ether, and other cryptocurrencies. Your order is placed alongside other buy and sell orders in the order book.

Exchanges and online brokers often charge fees for their services, depending on your platform (an exchange, an investing app, or a cash app). Crypto trading is usually more expensive than traditional markets, where many fees have decreased in recent years. For example, fees as high as 5% per trade or more are relatively uncommon, though many are much lower: 0.5 percent or less per deal.

Crypto Exchange vs. Crypto Wallet

Consider crypto exchanges as platforms where you can trade crypto assets and crypto wallets, a place where you can “store” crypto, though the latter is a little more complicated.

How Does a Crypto Wallet Work?

Crypto is not only digital but also decentralized; it is built on a blockchain, which is a distributed network of computers that creates and manages most types of cryptocurrency. You can use a crypto wallet to access and transact with your cryptocurrency on the blockchain.

The wallet program creates two public and one private key that you can use to send, receive, and manage your cryptocurrency. A “hot wallet,” stored on a computer or other internet-connected device, or a “cold wallet,” held on a piece of hardware such as a flash drive, can be set up.

While most wallets will accept a variety of crypto, not all of them will double-check before buying or sending crypto.

How do Crypto Wallets and Crypto Exchanges Work Together?

Keeping your cryptocurrency on the exchange where you purchased it is arguably the simplest way to manage it, but it limits your options and can be less secure, as exchanges are prone to cyber assaults or hacks.

The majority of exchanges are unregulated, and just a few provide insurance in the event of theft, fraud, or failure. You could lose your crypto if an exchange goes out of business, as two did recently in Australia in October and December 2021.

Setting up your cryptocurrency wallet can provide more protection for those who want a more secure option. Using a wallet is a bit more complicated, but the extra peace of mind is worth the trouble for some investors.

Different Types of Exchanges

Centralized Exchanges

These exchanges feature a third party that assists with transactions to ensure they go through as planned as a brokerage.

This may seem contradictory, given that one of the foundations of cryptocurrencies is that they are neither issued nor regulated by a government or other central body. On the other hand, a centralized cryptocurrency exchange can make purchasing your desired cryptocurrency with common currency easier.

The risk associated with these centralized exchanges is that because a single party holds them, they are more vulnerable to assault.

Decentralized Exchanges

A decentralized cryptocurrency exchange, or DEX, works without third-party centralized exchanges. Because they are open source and rely on users to trade peer to peer, decentralized exchanges are closer to the spirit of the bitcoin industry.

A decentralized cryptocurrency exchange may be safer than a centralized cryptocurrency exchange. Because there is no central institution or system to hack, stealing cryptocurrency is more complicated. Fees may be lower in a DEX, and transactions may be processed faster.

When compared to centralized exchanges, a DEX may have some disadvantages. Because a DEX may not allow straightforward transfers from bank accounts or debit cards to buy bitcoin, you may need to be more tech-savvy.

Some DEXs don’t allow you to exchange fiat currency at all, leaving you with the choice of trading one cryptocurrency for another. Since there is no central authority, your funds are not insured, and there is no one to contact if you have a customer care issue.

Hybrid Exchanges

Hybrid cryptocurrency exchanges attempt to blend the best of both worlds from centralized to decentralized into one exchange. They aim to give end-users the convenience of a centralized exchange while also giving them the security and freedom of a decentralized exchange.

Hybrid exchanges have struggled to achieve the same level of adoption as centralized exchanges. Nonetheless, they may build the groundwork for a future middle ground that will satisfy consumers and crypto enthusiasts.


A crypto exchange may appear straightforward — it’s a platform where you can buy and sell various forms of cryptocurrency. Still, exchanges may be sophisticated like most things in the crypto-verse. They may necessitate a little more vigilance from users than regular stock and bond exchanges.

The most important thing to know is that this industry is mostly unregulated, including the coins, platforms, blockchains, exchanges, and wallets. This implies that the consistency you’re used to in the traditional financial world, in terms of how assets are organized and how investment firms operate, is less frequent in the cryptocurrency sector. As a result, taking your time to learn the basics — such as whether a given exchange can run in your state or nation, what fees they charge, and so on — as well as more sophisticated topics like choosing the correct wallet — is critical.

Fortunately, the cryptocurrency market is rapidly expanding, and an increasing number of businesses are making things easier for investors.
