What makes a crypto exchange safe? Key security features explained

We look at how cryptocurrency exchanges protect their users and guard against hacks, and what to look for in a safe crypto exchange. Protect your assets and trade safely with these tips.

A safe crypto exchange is one that uses state-of-the-art encryption, maintains a comprehensive compliance program, conducts regular security audits, and goes out of its way to protect its users. In this guide, I’ll show you how these exchanges work.

Are crypto exchanges safe?

Hacks are probably the first thing that jumps to mind when questioning the safety of crypto exchanges. In 2025, hackers stole 1.4 billion USD worth of ETH, and a year earlier, they stole over half a billion from WazirX and DMM Bitcoin. If hacks are common, how safe are crypto exchanges?

The truth is, hacks and data breaches are common. What’s more, there are hundreds of exchanges worldwide, all holding billions of dollars in cryptocurrencies. So, while major hacks are alarming, they’re rare.

There’s always a risk, but a safe crypto exchange will mitigate that risk.

In addition to user safety, investors should also account for high volatility, as seen here in a chart comparing BTCUSD (red and blue bars) to GBPUSD (red line).

Protocols used by safe crypto exchanges

A safe crypto exchange often relies on advanced encryption to protect users and transactions. AES-256 encryption is commonplace and is considered the most secure encryption standard. 

Other systems and processes keeping crypto exchanges secure include:

KYC and AML requirements

Regulators require platforms to implement strict Know Your Customer (KYC) and Anti-Money Laundering (AML) systems and to verify every user’s identity, thereby maintaining a safe trading environment.

Most modern KYC/AML systems are automated, and they check a user’s data against publicly available information, such as credit reports.

Secure private keys

Hackers often target private keys, but many exchanges now secure them using multi-party computation (MPC). It swaps the traditional, single-point-of-failure method for a multi-step, multi-party approach.

Security audits

As exchanges close one door, hackers open another, locking them in a constant cat-and-mouse game. A safe crypto exchange will conduct regular security audits to assess its systems and processes and identify vulnerabilities. 

Fraud detection software

The best exchanges take a proactive stance against fraud, using fraud-detection software to monitor for signs of fraudulent activity. Driven by machine learning algorithms, these systems are taught how to identify and flag suspicious patterns.

Cold storage

Many crypto exchanges keep the majority of their crypto assets in cold storage, meaning the wallets are offline. It greatly reduces the risk of theft from hacks, phishing attempts, and malware attacks.

Employee and user education

The ever-evolving nature of crypto scams and security methods means exchanges must constantly educate their employees, while also providing helpful guides to their users. Employees should be updated on the latest scam methods, particularly those targeting high-level staff (such as phishing).

How crypto users can protect themselves on a safe crypto exchange

Is cryptocurrency safe? Well, it’s as safe as you make it. The exchange takes a lot of the responsibility, but some of that burden falls on the user. The safest platform in the world can’t protect you if you send your login details and private keys to anyone who asks for them.

Here are a few ways you can protect yourself when using a safe crypto exchange:

• Create long, unique passwords.
• Add two-factor authentication.
• Set anti-phishing codes in your account settings, so you know when an email is genuine.
• Use “Address Whitelisting” to ensure funds can only be sent to pre-approved wallets.
• Create a separate email address for the exchange.
• Don’t use public Wi-Fi to access your account.

Whether you’re trading and using stop loss/take profit orders (as above in the Exness Terminal) or buying from a crypto exchange, always protect your capital and mitigate risk where possible.

What to avoid in a cryptocurrency exchange

Now you know what a safe crypto exchange looks like, what are the red flags of an untrustworthy crypto exchange? There are many out there, and if you want to keep your transactions and assets safe, you need to avoid them.

This is true whether you’re using an exchange, a crypto/forex trading site, or any other platform that’s holding your money and asking for your trust. Some of the main things to avoid include:

Weak regulatory compliance

KYC and AML checks can be frustrating, but they exist for a reason. If an exchange rushes you through registration, doesn’t request much information, and doesn’t have a thorough KYC process, they might be ignoring regulations. 

Minimal user protection

A safe crypto exchange should encourage you to use a long, complex password and two-factor authentication, thereby demonstrating that it prioritizes your security. 

Unrealistic claims

Regulated, trusted exchanges are honest and compliant. They should warn you that cryptocurrencies are volatile, while encouraging responsible crypto trading. If they’re ignoring those requirements and making grand claims about “making money”, it could be a scam.

Exness encourages responsible trading by offering stop loss/take profit orders and educating traders on strategies and upcoming economic events (see on the left of this Exness Terminal screenshot).

Trading glossary

Encryption

Encryption is the process of converting information into code to prevent unauthorized access during transactions and data storage.

Cold storage

Cold storage means keeping cryptocurrency wallets offline to protect them from online hacks and cyberattacks.

KYC (Know Your Customer)

KYC is a process by which exchanges verify users’ identities to prevent fraud and money laundering, and to comply with regulations.

AML (Anti-Money Laundering)

AML refers to rules and processes that prevent criminals from using crypto exchanges to hide or move illegal money.

Two-factor authentication (2FA)

2FA is an extra security step requiring users to provide two forms of identification before accessing their account.

Private key

A private key is a secret code that allows users to access and control their cryptocurrency holdings.

Regulatory compliance

Regulatory compliance means the exchange follows legal rules and standards to protect users and ensure safe trading practices.

Final thoughts: What is a safe crypto exchange?

Cryptocurrency exchanges are generally safe places to buy and sell digital assets, but safety ultimately depends on both the platform and the user. Reputable exchanges invest heavily in security features such as encryption, cold storage, and regulatory compliance, yet it’s still essential for traders to verify a platform’s credibility and track record before depositing funds.

At the same time, users play a major role in protecting their own accounts. Keeping passwords secure, enabling two-factor authentication, and safeguarding private keys are critical steps. If you’re new to crypto or want to build confidence before trading with real funds, consider starting with a free demo trading account where you can practice trading strategies in a risk-free environment.

Frequently asked questions

How do you tell if a crypto exchange is safe?

Make sure it is licensed (look for pages like this Exness regulations list) and offers safety protocols such as multi-factor authentication.

How can you tell if a crypto exchange is legit?

In addition to checking for a license, you should also check reviews by searching for the exchange's name followed by words like “scam” and “review”.

Will a crypto exchange give me my money back if it’s hacked?

Some of the larger exchanges have policies in place to cover such events, but it’s unlikely you’ll get your funds back on a smaller exchange.
