What You Need to Know?

Cryptocurrencies such as Bitcoin, Ethereum or, most recently, Solana are household names in this digital age. But in order to get your hands on and trade those digital assets, you need a crypto exchange. If you are a novice looking to make your first purchase, or an experienced trader juggling a diverse portfolio of digital assets, knowing how crypto exchanges function is essential.

What Is a Crypto Exchange?

A crypto exchange is an online platform that enables its users to purchase, sell, and trade cryptocurrencies. These exchanges function very similarly to stock exchanges, except instead of using stocks and bonds as their investment medium, it’s digital currency.

Crypto exchanges are the plumbing of buyers and sellers up and down the stack, allowing price discovery and ensuring buyers and sellers can engage with each other in a secure context. Many also provide other services, like staking, margin trading, futures and access to NFTs.

Do you really need a Crypto Exchange?

Without exchanges, it would be hard for nearly everyone to obtain cryptocurrency. These platforms provide:

Wide range of digital assets available for trading

Real-time pricing and trading

Secure pockets to safeguard all of your wealth

Fiat -> Crypto payment gateways

Market analysis tools used in market trading

They’re the lifeblood of the crypto ecosystem, in short.

Types of Crypto Exchanges

Crypto exchanges fall into one of two categories: Centralized (CEX) and Decentralized (DEX).

Centralized Exchanges (CEX)

These are run by businesses and act as middlemen between the buyers and the sellers.

Examples: Coinbase, Binance, Kraken, Gemini

Pros:

High level of liquidity and rapid execution of any transaction

Simple and beginner-friendly interfaces

Customer service and fiat on-ramp

Advanced trading options (e.g., stop-limit orders, futures)

Cons:

Users don’t hold their private keys

Exposed to regulations scrutiny and hacks

Decentralized Exchanges (DEX)

DEXs are peer-to-peer exchanges which enables users to make trades directly from their wallets without a mediator.

Examples: Uniswap, Pancake Swap, Sushi Swap So-called “decentralized exchange aggregation” is the practice of swapping a pair of tokens across several decentralized exchanges at once, and then selecting the best quote for the trade.

Pros:

Full control of your assets

Lower fees

No KYC required

Cons:

Lower liquidity

Fewer user protections

Technical interface could overwhelm newcomers

Supported Coins

Some exchanges are limited to only the most popular cryptocurrencies, while others have hundreds of altcoins. Select the one that suits your investment objectives.

Trading Fees

Exchanges make money from trading fees. These could be:

Flat per trade

The maker-taker model on trading volume

Deposit and withdrawal fees

Shop fee structures before you invest.

Liquidity

More liquidity is better because trades are executed faster and at better prices. Binance and Coinbase are both popular for high liquidity.

Fiat Support

If you’re looking to purchase crypto with your local currency, such as U.S. dollars (USD) or euros (EUR), also confirm whether the exchange accepts fiat deposits through bank transfers, debit cards or payment apps.

Customer Support

Good customer service is important all the more so after a few weeks of market tumult. Find live chat, email, or at least phone support if possible.

Sign-up via your email and make a solid password. KYC is often required for centralized exchanges.

Step 3: Buy or Trade Crypto

Select a trading pair (ex: BTC/USDT), a market or a limit order and trade your order.

Step 4: Secure Your Holdings

Potentially look into moving it into a private wallet, especially if you are just holding for the indefinite future.

Typical risks and how to mitigate them

Hacks: Trade on exchanges with good security practices and keep large holdings in cold wallets.

Regulatory Risks: Only use regulated platforms that abide by the laws in your country.

Scams: Stay away from platforms that guarantee profits or that engage in aggressive marketing.
