Where To Trade Crypto?

Your Guide to Centralized and Decentralized Exchange

If you’ve just entered crypto, you’ve probably heard people say things like “Don’t keep your coins on an exchange” or “Not your keys, not your crypto.”

But what does that really mean?
And if centralized exchanges are risky, why does everyone still use them?

Let’s unpack this together

---

What is a CEX? (Centralized Exchange)

A Centralized Exchange (CEX) is basically a company that lets you buy, sell, and hold crypto, just like a bank helps you manage money.

You create an account, deposit funds from your bank, and trade through their app or website.

Examples: Binance, Coinbase, Kraken, Crypto.com

When you use a CEX, the crypto you buy is stored in their custody.
You don’t directly hold your wallet or private keys — the exchange does.

That’s where the saying comes from:

“Not your keys, not your crypto.”

If a CEX goes bankrupt, freezes withdrawals, or gets hacked, your funds can be at risk.
We saw this happen with FTX, Mt. Gox, and others — billions lost overnight because users didn’t control their keys.

Still, CEXs are popular for a reason. They’re simple, familiar, and beginner-friendly.

✅ Pros of CEX

• Easy to use

• Allows fiat deposits and withdrawals

• High liquidity (fast trades, stable prices)

• Customer support if something goes wrong

⚠️ Cons of CEX

• You don’t control your crypto

• Risk of hacks or platform collapse

• KYC and privacy trade-offs

• More Expensive

What is a DEX? (Decentralized Exchange)

A Decentralized Exchange (DEX) lets you trade directly from your own wallet — no company, no account, no middleman.

Think of it as peer-to-peer trading powered by smart contracts.

Instead of trusting a company, you trust code on the blockchain.

Examples: Uniswap, PancakeSwap, SushiSwap, Jupiter (on Solana)

To use a DEX, you connect your wallet (like MetaMask or Phantom) and trade directly on-chain.
You always keep control of your crypto.

That’s true freedom — but it also means full responsibility.
If you lose your wallet, send funds to the wrong address, or click a fake link, you can lose all your crypto.

✅ Pros of DEX

• You own your crypto

• No KYC or account setup

• Lower Fees that saves you a lot if you are trading frequently

• Early access to new tokens and projects

⚠️ Cons of DEX

• Less beginner-friendly

• Does not allow FIAT deposit. You have to buy crypto with crypto.

• No customer support

• Easy to make costly mistakes

The Truth: You’ll Probably Use Both

In today’s world, most people need both.

You still rely on CEXs for:

- Buying crypto with your local currency
-Cashing out to your bank account
-Using cards or e-transfers for quick purchases

And you use DEXs for:

-Self-custody and control
-Exploring DeFi, NFTs, or early-stage tokens
-Staying independent of middlemen

The Smart Approach

Use CEXs for convenience and DEXs for control.

Here’s a simple way to balance both:

1. Use a CEX like Coinbase or Kraken to buy crypto with fiat.

2. Transfer it to a self-custody wallet (MetaMask, Phantom, or Ledger).

3. Use a DEX to trade directly on-chain when you’re ready.

4. Keep only what you actively trade on the exchange.

That gives you the best of both worlds — the safety of self-custody and the practicality of centralized services.

The Takeaway

Crypto gives you the power to own your money directly — but that power comes with responsibility.

As the saying goes:

Not your keys, not your crypto.

But also remember:

Not your care, not your safety.

A balanced setup is ideal.
Keep your long-term assets in self-custody and use CEXs for fiat on- and off-ramps until the decentralized world matures.

We’re still early. Learning to manage both safely is part of becoming crypto native.
