Do you really own your crypto—or are you just borrowing it?

If your crypto is stored on a centralized exchange (CEX), the answer might surprise you. Technically, you don’t fully control it. The exchange holds custody of your assets, not you.

CEXs like Coinbase or Kraken are owned and operated by a central authority. They hold your crypto in custodial wallets, and they’re the ones in charge of managing the private keys to your account. To comply with Anti-Money-Laundering regulations, they usually require you to go through Know-Your-Customer procedures and ask for your ID before they let you set up an account.

Centralized exchanges are popular for a reason. They offer fast and straightforward onboarding, a smooth user experience, and high liquidity. For beginners, they simplify the process of trading crypto and reduce the risk of scams or failed transactions. But they do come with a trade-off.

If you use a centralized exchange for trading crypto, you’re trusting the platform to manage your assets. It can suddenly freeze your account or restrict withdrawals and impose spending limits on your transactions. In the worst-case scenario, if the exchange ever gets hacked or goes bankrupt, you would lose all your crypto.

If you want more control over your funds, you can opt for decentralized exchanges (DEXs) like Uniswap and PancakeSwap. With a DEX, you trade with other crypto users directly from your wallet with no middleman or central authority to facilitate the transaction. That gives you full control of your crypto. You don’t need to go through KYC procedures to verify your identity, and you don’t rely on a platform to manage your funds.

However, full control also means full responsibility. If you lose your seed phrase or sign a malicious transaction, there’s no customer support to bail you out. DEXs have many functions and give you more flexibility than a CEX, but they should be approached with extra caution. Compared to CEXs, they also tend to be more complicated to master.

So, which one is better, a CEX or a DEX? The answer depends on your particular needs as a crypto trader. If you value convenience, CEX platforms may be more suitable. If you prioritize ownership and privacy, then DEXs give you full control. 

Use a CEX when:

• You're new to crypto and need a simple interface
• You want to convert fiat (e.g., USD) to crypto
• You prefer an exchange with AML compliance and insurance for your assets
• You need access to high liquidity or advanced features
• You don’t want to risk getting irreversibly locked out of your account if you lose your seed phrase

‍

Use a DEX if:

• You want full control of your funds
• You want to avoid losing all your funds if the owner of a centralized exchange goes bankrupt
• You’re trading tokens not listed on CEXs
• You want to trade in a peer-to-peer crypto marketplace where you get to choose the fees and rates you want
• You value privacy and decentralization

But what if you want the best of both worlds?

If you want the flexibility of having both CEX and DEX tools to choose from, you can pick an exchange that doubles as a CEX or a DEX, like OKX. These kinds of exchanges let you stay in control of your private keys while also letting you trade across both centralized and decentralized platforms. Leading exchanges like OKX support multiple chains, connect seamlessly with dApps, and offer comprehensive trading tools and features without sacrificing security.

In crypto, there’s a saying: “Not your keys, not your crypto.” Understanding who really controls your assets is key to protecting your funds. To become a successful trader, choose an exchange that gives you the tools you need to do it conveniently, securely, and on your own terms.
