A crypto exchange can make buying and selling simple, but it also puts a tempting target in front of criminals. Most losses don't start with a dramatic platform hack. They start with a fake login page, a weak email password, a rushed withdrawal, or a support scam in a social media inbox. Good exchange security is mostly routine: choose carefully, lock down your account, check every transaction, and keep only active trading funds online. The boring habits are the ones that protect you.
Choose an Exchange You Can Actually Verify
Start with the legal entity behind the exchange, not its adverts or follower count. A credible platform clearly identifies its company, operating regions, fees, custody approach, and support channels. Check whether it is authorised or registered where you live, then confirm that information through the relevant regulator's public register. A badge on a website proves nothing.
Read recent independent reports, especially those covering withdrawal delays, account closures, customer support, and security incidents. Every large exchange receives complaints, so look for patterns rather than one angry post. Repeated reports of frozen withdrawals without clear explanations are a serious warning.
Be sceptical of exchanges promising guaranteed returns, unusually high deposit rewards, or zero risk yield. Those claims are designed to override caution. Also check that the exact web address and mobile app publisher match the official links provided by the company. Search ads, app store clones, and lookalike domains are common routes into theft. If basic ownership and regulation are hard to verify, don't deposit money just because the interface looks polished.
Secure the Account Behind Your Account
Your exchange login is only as safe as your email account. Use a unique, long password for both, stored in a reputable password manager. Reusing a password from a shopping site or old forum is an avoidable mistake. If that site leaks credentials, attackers will try them on exchange and email logins within minutes.
Turn on two factor authentication using an authenticator app or, better still, a passkey or hardware security key if the exchange supports it. SMS codes are better than nothing, but phone number takeover fraud is real. Protect your mobile account with a carrier PIN as well.
Save backup codes offline, ideally in a secure physical location. Don't keep screenshots of them in your photo library or cloud notes. Review active sessions and authorised devices every few months, remove anything unfamiliar, and enable login and withdrawal alerts. A withdrawal address allowlist can add friction, which is exactly the point. It may stop a thief from sending funds immediately after breaking into your account.
Treat Every Deposit, Trade and Withdrawal as Final
Crypto transfers usually cannot be reversed. That means checking details is part of the job, not an optional extra. Before sending funds, confirm the asset, the network, and the full destination address. Similar token tickers and incompatible networks catch people constantly. Send a small test transaction first when using a new address or moving a meaningful amount.
Never copy an address from a chat message, pop up, search result, or supposed support agent. Malware can replace copied wallet addresses in your clipboard. Check the first and last characters on screen, and use address book entries only after independently verifying them.
Watch for phishing during busy periods. A message claiming there is a problem with your account may link to a convincing clone that captures your password and two factor code. Open the exchange from a saved bookmark or type the address yourself. Real support staff don't need your password, recovery phrase, remote access to your computer, or a transfer to "verify" your wallet. Anyone requesting those things is trying to steal from you.
Keep Trading Funds Separate From Long Term Holdings
An exchange is useful for trading, converting assets, and receiving payments. It is not the best place to hold money you do not need to trade. The platform controls the private keys to exchange balances, and access can be affected by a security incident, compliance review, technical outage, or insolvency. Proof of reserves can be informative, but it is not the same as a full audited balance sheet or customer protection scheme.
Keep an amount on the exchange that matches your actual trading needs. For longer term holdings, consider self custody only if you understand how to secure a wallet and back up its recovery phrase. Self custody removes exchange counterparty risk, but it makes you responsible for every error. Lose the recovery phrase or approve a malicious transaction, and there is usually no help desk to call.
Review your balances, connected apps, API keys, and withdrawal settings regularly. Delete trading bots and API permissions you no longer use. Security is not a setting you switch on once. It is a habit of reducing the number of ways somebody can move your money.
Is two factor authentication enough to protect an exchange account?
No. It helps, but you still need a unique password, a secured email account, phishing awareness, and withdrawal protections. An authenticator app, passkey, or hardware key is generally safer than SMS codes.
Should I keep all my crypto on an exchange?
No. Keep funds needed for active trading on the exchange and consider another storage method for longer term holdings. Make sure you understand self custody before moving large amounts.
What should I do if I think my account was compromised?
Change your email and exchange passwords from a clean device, revoke sessions and API keys, disable withdrawals if possible, and contact the exchange through its official website. Record transaction IDs and suspicious messages.
