by Cryptocurrency exchanges play a central role in the world of digital finance. If you’ve ever bought, sold, or traded Bitcoin, Ethereum, or any other coin, chances are you’ve used a crypto exchange. But what exactly are these platforms, and how do they work?
Let’s explore everything you need to know about crypto exchanges.
What is a Crypto Exchange?
A crypto exchange is an online platform that allows users to buy, sell, and trade cryptocurrencies. Some also allow trading between cryptocurrencies and traditional fiat money (like USD, EUR, INR).
Just like a stock exchange lets people buy and sell shares, a crypto exchange lets users trade coins such as Bitcoin (BTC), Ethereum (ETH), and thousands of others.
Types of Crypto Exchanges
There are two main types:
1. Centralized Exchanges (CEX)
These are operated by companies and act as intermediaries between buyers and sellers.
Examples:
- Binance
- Coinbase
- Kraken
- WazirX (India)
Pros:
- Easy to use
- High liquidity
- Customer support
Cons:
- Users don’t fully control their crypto (the exchange holds your private keys)
- Can be vulnerable to hacks
2. Decentralized Exchanges (DEX)
These are peer-to-peer platforms where users trade directly from their wallets.
Examples:
- Uniswap
- PancakeSwap
- dYdX
Pros:
- You control your own crypto
- More privacy, no KYC required
Cons:
- Slower, lower liquidity
- More technical knowledge needed
