Today, we answer a very common beginner question:
👉 Where do people actually buy and trade crypto?
There are two main types of exchanges:
Centralized Exchanges (CEX)
Decentralized Exchanges (DEX)
Let’s keep this simple.
---
What Is a Centralized Exchange (CEX)?
A centralized exchange is a platform run by a company.
Think of it like a crypto bank or app.
Example:
Binance
On a CEX:
You create an account
You log in with email & password
The platform helps manage trades
Why beginners like CEXs:
Easy to use
Simple buy & sell buttons
Customer support
Clear interface
📌 Important note:
The exchange holds your crypto for you.
---
What Is a Decentralized Exchange (DEX)?
A decentralized exchange has no central company controlling it.
It runs directly on the blockchain.
Example:
Uniswap
On a DEX:
No account needed
You connect a wallet
You trade directly from your wallet
Why DEXs exist:
More control
More privacy
No middleman
📌 But:
DEXs can feel confusing for beginners.
---
So… CEX or DEX? (Beginner Truth)
Both are important in crypto.
But for beginners:
CEX = simpler
DEX = more advanced
Starting on a CEX helps you:
Learn without stress
Avoid early mistakes
Understand trading basics
You can explore DEXs later, when you’re ready.
---
Final Takeaway
> Beginners should start with centralized exchanges.
Decentralized exchanges come later.
Learning first is more important than rushing.
