## What You Need to Know About Centralized Exchanges Before Getting Started

Cryptocurrency trading has become one of the most attractive fields for investors in recent years. However, due to the highly volatile nature of this market, beginners need to understand the trading tools they use. To start your trading journey, the first step is choosing a suitable platform. Currently, the market offers two main types of exchanges: **centralized exchanges** (CEX) and **decentralized exchanges** (DEX). Each has its own distinct features that need to be understood.

## What Is a CEX and Why Has It Become a Popular Choice?

A **centralized cryptocurrency exchange**, or **CEX**, operates under the management and operation of a dedicated agency or company. This type of exchange was the earliest in the history of crypto trading, initially allowing users to operate anonymously. However, as the industry developed, global financial regulators began requiring **exchanges** to perform identity verification of users (KYC) to comply with regulations.

Today, CEXs are renowned for the advanced trading features they offer. Users can access **limit orders**, **stop-loss orders**, **margin trading**, and **leverage trading** to optimize their strategies. Security systems typically include storing most assets in **offline cold wallets** (offline), with only a small portion kept in hot wallets to support **liquidity**. This approach helps reduce the risk of asset loss.

## How CEX Works

Using a CEX is similar to a traditional banking system. You need to register an account, verify your identity, and deposit funds. After completing these steps, you can place **market orders** into the exchange’s **order book**.

When your buy order matches with a sell order from another trader, the transaction is executed immediately. CEXs act as intermediaries between you and other traders. To sustain operations, the exchange charges a **trading fee** on each transaction, which is their main revenue source.

Besides order matching, CEXs also serve as **payment overseers**, protecting the identities of parties by processing transactions through the platform instead of directly between buyer and seller. CEXs also hold your cash and **cryptocurrency** until you actively withdraw to your personal wallet.

## Benefits of Using a CEX

CEXs remain dominant for many practical reasons. The **user interface** of modern exchanges has been optimized so that even first-time users can operate easily. They provide robust customer support, giving users confidence when trading in a protected environment.

In case of security breaches, most CEXs are responsible for compensating affected users. Moreover, many exchanges offer integrated services such as **staking**, NFT marketplaces, project launchpads, P2P trading, etc., helping users manage their entire asset portfolio in one place.

## Risks You Need to Be Careful Of

Despite many advantages, CEXs still carry significant risks. Although large exchanges invest heavily in **security protocols**, hacks can still occur. In many cases, human error is the main cause rather than system failure. For this reason, you should withdraw your funds to a personal wallet after completing transactions. Even better, use a **hardware wallet** (hardware wallet) for long-term storage, which is considered the safest method.

**Trading fees** are costs you must accept when using a CEX, whether buying or selling. Although fees are usually low, they can increase over time.

The biggest issue is that you must give control of your assets to the exchange. As the popular saying in the crypto community goes: "Not your keys, not your coins." Since CEXs hold private keys, they can seize or freeze your account at any time, reducing your actual control.

## What Is a DEX — The Alternative to Centralization

As the cryptocurrency industry evolved, many realized that centralization does not align with the spirit of **blockchain** and cryptocurrencies. Thus, **decentralized exchanges** (DEX) emerged. **What is a DEX**? It is a trading platform not managed by any entity, built entirely on **smart contracts** and operated by the community.

Initially, DEXs faced major issues with **liquidity** instability. However, the advent of **Automated Market Maker** (AMM) technology revolutionized DEXs. Today, users can provide liquidity by staking coins and tokens, earning rewards in return.

## How DEXs Differ in Operation

Unlike CEXs, DEXs do not require you to deposit funds into an account. Instead, you connect your personal wallet directly to the platform. DEXs do not use traditional **order books** but rely on **automated market maker** mechanisms to price and execute trades.

Suppose you want to trade tokens on the **Ethereum** blockchain. You access an Ethereum-based DEX, connect your wallet, and send an order. The **smart contract** completes the transaction using funds from the liquidity pool, then directly transfers tokens into your wallet without the need to deposit or withdraw funds. You also do not need to create an account, reducing entry barriers.

## Current Limitations of DEXs

Despite their decentralization, DEXs still have some limitations. **Liquidity** can often be unstable, user interfaces are more complex than CEXs, and they cannot directly convert **cryptocurrencies** into fiat currency or vice versa. These issues are gradually being addressed, but currently, CEXs are more convenient.

## Should You Choose CEX or DEX?

The choice depends on personal needs. CEXs are more convenient, better supported, and suitable for beginners. DEXs offer decentralization, freedom, and higher security, fitting those who prioritize control over their assets. Over time, DEXs will become easier to use, but currently, CEXs lead in user experience.
