Diferenças entre exchanges centralizadas e Descentralizadas: qual é melhor em 2024?

If you are a cryptocurrency trader or a Bitcoin futures trader , it is essential to understand the difference between a decentralized and a centralized exchange.

What is a cryptocurrency exchange?

Before we move on to explaining the concepts of centralization and decentralization, let's briefly examine what a cryptocurrency or derivatives exchange is.

One cryptocurrency exchange is a platform that allows you to buy and sell a variety of virtual currencies. So a trader would design his strategy based on which coins appear to be increasing in value and which ones are falling. The objective is to make a profit with each trade or to hold a coin until the price increases to the desired amount.

Likewise, a derivatives exchange also allows you to buy and sell assets. However, instead of dealing directly with cryptocurrencies, you deal with contracts that derive their value from an underlying asset. For example, the BTCUSDT contract by Binance or kucoin follows the price of Bitcoin. Bitcoin futures trading allows you to open positions in an attempt to profit by predicting whether the price of Bitcoin will rise or fall without having to hold on to Bitcoin.

what is a Centralized cryptocurrency exchange how it works?

Centralized exchanges are trading platforms that can be compared to brokers and stock exchanges in the way they operate. They were responsible for maintaining much-needed liquidity for the cryptocurrency markets as they made cryptocurrencies much more accessible to the masses.

Centralized exchanges are operated by multiple companies that maintain full control over all transactions as well as users' private keys and details and wallets your trading accounts. This brings us to the main criticisms of centralized exchanges, namely the fact that users have to go through specific company-approved methods to handle their funds and the implied transactions.

In recent years, several cryptocurrency exchanges have been hacked, resulting in millions of dollars lost (main examples are Binance, Upbit, Bithumb, cryptopia, etc.). Not only that, but centralized exchanges are also prone to government bans, and often have poor support sections (even though most exchanges are actively working on resolving this issue).

However, by far the biggest “problem” with centralized exchanges is the necessary compliance with the KYC and the implicit sending of identity documents. This opens the door to the possibility of identity theft and even leakage of personal identity information.

What is a Decentralized Cryptocurrency Exchange how dex works

Decentralized exchanges are much more in tune with what Satoshi imagined, as no company operates these DEXs, as they are often referred to. In fact, decentralized exchanges operate with the help of the same technology that powers most cryptocurrencies, the  blockchain so the DEXs are considered the exchanges of the future . These exchanges do not contain customer cryptocurrencies and do not store sensitive information.

As they are entirely blockchain-based, it is only natural that decentralized cryptocurrency exchanges suffer from most of the inherent disadvantages of blockchain, chief among them being scalability. Therefore, most decentralized exchanges are slower than centralized exchanges. Not only that, but they are also arguably less user-friendly when compared to their centralized counterparts.

However, as technology advances, decentralized exchanges are likely to improve. Liquidity levels will increase and user experience will improve mainly due to technologies like smart contracts, off-chain atomic swaps, and on-chain atomic swaps.

Decentralized vs Centralized Exchange: Real Differences Between CCEs and DEXs

The most obvious difference is the general levels of popularity. Right now, DEXs are much less popular than their centralized peers. This means that, in terms of trading volume, CCEs are also the leaders of the group. CCEs also have better liquidity. Another big difference is the fact that DEXs accept cryptocurrency payments and only exchange cryptocurrencies, while CCEs also tend to allow exchanges between cryptocurrencies and crypto as well as accepting direct bank transfers and credit/debit card payments.

On the other hand, since their nodes are distributed, DEXs generally have a lower risk of hacks. The same can be said about government actions, as DEXs are immune to government intervention. DEXs also have an advantage when it comes to the level of privacy provided. All transactions are anonymous, while in CCEs, there is an increased risk of identity theft and hacks. All cryptocurrency exchanges in fiat currencies are mainly done on centralized exchanges. This is mainly because the EUR and USD (all other fiat currencies) are also centralized.

Conclusion: decentralized or centralized exchanges

Choosing between a centralized or decentralized cryptocurrency exchange is not a difficult situation. Given that both types of exchanges have undeniable advantages and both have notable disadvantages. Currently, it is clear that centralized exchanges provide more utility and functionality to your users. The structure of the cryptocurrency ecosystem remains, at least for now, unchanged. Centralized exchanges are still kings in terms of daily trading volumes and the most preferred by users are the Binance, kucoin, hitbtc.

However, decentralized exchanges will soon be able to defend themselves against their centralized peers. As technology advances, decentralized exchange UIs will continue to improve, pair trading options will grow, and soon after, the differences between centralized and decentralized exchanges will become less apparent.

One thing is for sure, security becomes a very strong focal point for most crypto-related exchanges. So the improved security will certainly be a very good incentive for mass adoption purposes. In short, security will be a very attractive selling point for decentralized exchanges.
