What Are the Benefits of Using a CEX?
CEXes are expensive to use and may well run counter to the spirit of blockchain technology, but they do have a number of key benefits, namely the following:
A big CEX makes its money from having enough fiat and assets in reserve to let you make instantaneous deposits and withdrawals. If you want to swap your BTC for USD, for instance, you would expect to be able to do that in seconds with a CEX…or you’d take your custom elsewhere.
Liquidity is a CEX’s trump card, some would argue – and that is why they put so much effort into providing customers with all the high-speed liquidity they could possibly need.
Although high-profile hacks were once common in the world of crypto, it appears that many of the bigger exchanges are finally learning their lesson. While it’s certainly true that exchanges used to have almost laughably poor security systems, this is no longer true in most cases.
As such, the number of hacks executed on bigger crypto exchanges has fallen in recent years. Many also take out costly insurance policies that allow customers to recoup some or all of their lost funds in the event of a security breach.
In many countries, crypto exchanges have to apply for operating permits and prove their stability and competence to financial regulators. These same regulators are keen to bring crypto under the same kind of regulatory umbrella as exists for tradfi institutions such as banks.
As such, they are monitored for irregular transactions and must implement investor protection measures. They also have to provide customers with risk notifications about the non-reversible nature of transactions and comply with government orders. If ensuring that your financial operations are conducted above-board and meet compliance standards, a CEX may be for you.
For most people, this is the real biggie. Creating user-friendly interfaces that even your grandmother could make her way around is a CEX’s priority. And because orders and custody are all centralized on their platforms, they let you make your trades in seconds. Sure, you pay more for that privilege, but if you just want to buy some BTC fast and don’t care about much else, a CEX usually has you covered.
What Is a Decentralized Exchange?
Put (perhaps overly) simply, a DEX can be like turning on advanced settings in an app. The app (the CEX in this metaphor) is set up to meet the needs of the most typical user who can’t be bothered over-thinking and interacting with their phone too much. But once you start tinkering with the settings and taking manual control, things get complicated – if sometimes better.
A DEX puts you in charge of your own tokens or fiat by letting you execute functions on a blockchain network directly. They do away with the central hub of the wheel so that there is no sole point of failure.
There’s no KYC here. And when it comes to prices, the DEX usually makes use of automated market maker technology that removes the need for a middleman body that regulates the price of coins. Algorithms – rather than employees – dictate how everything works.
You also need to take charge of your own private keys. A CEX usually handles this just like a bank manages your PIN. If you forget it, you can simply ask the CEX to send you a new one or reset it. If you are using a DEX and lose your private keys, your funds could become irretrievable – forever.
What Are the Benefits of Using a DEX?
DEXes can arguably bestow the following benefits on their users:
A better fit for decentralized tokens
Crypto runs on decentralized blockchain protocols, so it has long been an irony that trading them has been confined to centralized organizations that gate off direct blockchain access. If decentralized coins and decentralized finance (DeFi) are your thing, why would you want to involve something that resembles a tradfi bank or bureau de change in the picture?
What governments like least about crypto is elements of anonymity: anonymous wallets, anonymous transactions – and exchanges that allow users to operate under the radar. Proponents of crypto claim that the internet needs a native currency, and one that does away with governments’ rights to monitor, block or freeze transactions. It might sound a bit anarchic or utopian to some, but others like the fact that DEXes don’t require users to prove who they are and submit selfies and copies of documents like passports to faceless tech giant firms.
“Not your keys, not your coins” is the familiar battle cry of the crypto podcaster Antonio Pompliano. If you don’t control your own private keys, you can’t take charge of your custody. Your tokens may be sitting in a wallet attached to your login details and password on a CEX, but – like a bank – the funds you own aren’t actually in your possession. Do you trust yourself to look after your own assets or a tech company? The answer will likely determine whether or not you will use a DEX.
As there’s theoretically no middleman to pay with a DEX, you don’t need to worry about a platform’s bottom line. Ultimately, if a CEX becomes unprofitable for too long, it will go out of business. With a DEX, fees can often be much lower. Sometimes the liquidity problem means that DEXes have to team up with liquidity providers – a factor that can actually drive fees up. But for the most part, the lack of an intermediary does help reduce costs to traders in many instances.
A wider selection of tokens
CEXes are forever listing and delisting coins – again often due to regulations. In Japan, for instance, regulators get to approve or reject coins, a factor that leads to an often very narrow selection of tokens on centralized trading platforms. CEXes have a lot to lose if a token turns out to be a dud – and often have listing councils that spend days or weeks going through listing applications with a fine-tooth comb. That can ensure greater safety for users, but it can also hinder your ability to make your own choices in this regard. DEXes put the responsibility in your hands, again decentralizing the process.
So Which One Is Best for Me?
It would be great to end with a quick and easy answer, but as is the case with most things crypto-related, the answer is: it’s complicated.
Essentially, whether you choose a CEX or a DEX just depends on your needs: Do you want an easy, fuss-free system, or do you prefer advanced options and greater independence?
Crypto is divisive in many ways, and the choice of whether to use a CEX or DEX will inevitably put you on one side of the fence or the other – even if you have little interest in the CEX vs DEX controversy.
2022 prediction: the Great Crypto Schism
All cex forced to allow transfers to/from KYC’d wallets will erase cex<>dex arbitrage. First minor coins will start having significantly different prices on dex vs cex. Later, major coins as well, which will initiate the first CT scism. pic.twitter.com/B9pfsOLfsW

If you think you have better things to do with your time than fuss about with algorithms, blockchain networks and private key management, use a big, reputable CEX. But if you want deeper levels of control over the way you trade and want to explore a way to reduce your trading costs, maybe a DEX is worth looking into.
