🏦 CEX vs DEX 101 – The difference between centralized and decentralized platforms in trading
In the world of cryptocurrencies, trading platforms are used to exchange coins between users, and these platforms are divided into two main types:
Centralized platforms (CEX – Centralized Exchanges)
Decentralized platforms (DEX – Decentralized Exchanges)
In this lesson '101', we explain the basic differences between CEX and DEX, and outline the advantages and disadvantages of each type.
First: ⚙️ What are CEX – Centralized platforms?
CEX means 'Centralized Exchange', a centralized trading platform.
It is a platform managed by a company or central entity.
Popular examples: Binance, Coinbase, KuCoin, Bybit, OKX...
✅ Advantages:
User-friendly and fast interface.
High liquidity and great execution speed.
Technical support and additional protection services.
Offers advanced tools (Margin – Futures – Copy Trading...).
❌ Disadvantages:
The company controls your funds, and it holds the private keys (not your keys).
Vulnerable to hacking or government shutdown.
Identity verification (KYC) is required in most cases.
Second: 🔐 What are DEX – Decentralized platforms?
DEX means 'Decentralized Exchange', a decentralized trading platform.
No entity controls it; it relies on smart contracts.
Popular examples: Uniswap, PancakeSwap, SushiSwap, 1inch...
✅ Advantages:
No registration or identity verification needed (high privacy).
User retains their private keys.
Resistant to censorship and cannot be easily shut down.
❌ Disadvantages:
Liquidity is lower at times.
Network fees (gas fees) can be high.
Less easy for beginners.
No direct support in case of an error.
