The recent $22 million hack of UK-based cryptocurrency exchange Lykke on June 4, 2024, has sent ripples through the crypto community. With 158 Bitcoin and 2,161 Ethereum stolen from the platform’s wallet, many users — especially newcomers to cryptocurrency — are wondering: how safe are my funds on an exchange? If you are new to crypto or simply want to understand how to better protect your digital assets, this guide walks you through the essentials of exchange security in straightforward terms.
The Basics
When you buy cryptocurrency on an exchange like Binance, Coinbase, or Lykke, the exchange holds your private keys — the cryptographic codes that prove ownership of your coins and allow them to be spent. Think of it like keeping your money in a bank: you trust the institution to safeguard it. But unlike banks, cryptocurrency exchanges are not universally insured, and if they get hacked, your funds could be gone permanently.
The Lykke hack is a perfect example. The exchange had its wallet infrastructure compromised, and $22 million in customer assets was stolen. While Lykke promised to recover the funds using its capital reserves, history shows that such promises do not always materialize. The exchange halted all withdrawals and deposits, leaving users unable to access their own money.
Understanding this fundamental risk is the first step toward protecting yourself. The crypto community has a saying: “Not your keys, not your coins.” This means that if you do not personally control the private keys to your wallet, you are trusting someone else with your money.
Why It Matters
Cryptocurrency hacks are not rare events. In Q2 2024 alone, over $430 million was stolen across various crypto platforms. The largest incident was the $300 million DMM Bitcoin hack on May 31, followed by the Lykke breach just four days later. These are not small, obscure platforms — they are real exchanges serving real customers.
With Bitcoin trading around $70,500 and Ethereum near $3,800 as of June 2024, even small amounts of cryptocurrency represent significant value. A theft of just 1 BTC means losing over $70,000 at current prices. The financial impact of inadequate security can be devastating, particularly for individuals who have invested a substantial portion of their savings into cryptocurrency.
Furthermore, recovering stolen cryptocurrency is extremely difficult. Unlike traditional bank fraud where institutions can often reverse transactions, blockchain transactions are irreversible by design. Once your crypto is stolen, it is typically gone for good.
Getting Started Guide
The single most important step you can take to protect your cryptocurrency is to move it off exchanges and into your own wallet. Here is how to get started:
Step 1: Choose a wallet type. For beginners, a hardware wallet like a Ledger or Trezor provides the best balance of security and usability. These physical devices store your private keys offline, making them immune to online hacking attempts. Software wallets like MetaMask or Trust Wallet are free alternatives that still give you control of your keys, though they are somewhat less secure since they run on internet-connected devices.
Step 2: Set up your wallet. Follow the manufacturer’s instructions carefully. The most critical part is writing down your recovery phrase — a series of 12 or 24 words that can restore your wallet if your device is lost or damaged. Write this phrase on paper and store it in a secure location. Never photograph it, type it into a website, or store it digitally.
Step 3: Transfer your crypto. Send your cryptocurrency from the exchange to your wallet address. Start with a small test transaction to make sure everything works correctly before sending larger amounts. Double-check the destination address carefully — crypto transactions cannot be reversed if sent to the wrong address.
Step 4: Verify the transfer. Check that your crypto has arrived in your wallet by looking up your wallet address on a blockchain explorer. Once confirmed, you can feel confident that your funds are under your control.
Common Pitfalls
The biggest mistake new crypto users make is leaving all their funds on an exchange long-term. While exchanges are convenient for trading, they are not designed for secure long-term storage. Treat exchanges like a marketplace, not a vault — use them to buy and sell, then move your assets to your own wallet.
Another common error is falling for phishing attacks. Scammers create fake websites and emails that look identical to legitimate exchanges or wallet services. Always verify the URL in your browser before entering any credentials, and never click links in unsolicited emails or messages claiming to be from your exchange or wallet provider.
Sharing your recovery phrase with anyone is an absolute no. No legitimate service will ever ask for your recovery phrase. If someone asks for it, it is a scam — end of story. Store your recovery phrase offline and in a location only you can access.
Using weak or reused passwords on exchange accounts creates unnecessary vulnerability. Use a unique, strong password for each exchange account and enable two-factor authentication using an authenticator app rather than SMS, which can be intercepted through SIM-swapping attacks.
Next Steps
Once you have mastered the basics of self-custody, consider exploring advanced security measures. Multi-signature wallets require multiple approvals before funds can be moved, adding an extra layer of protection. Setting up a dedicated computer or using a privacy-focused operating system for cryptocurrency transactions can further reduce your attack surface.
Stay informed about security developments in the crypto space. Following reputable security researchers and news sources helps you stay ahead of emerging threats. The cryptocurrency landscape evolves rapidly, and security practices that were sufficient six months ago may need updating as new attack vectors emerge.
The Lykke hack serves as a wake-up call, but it does not mean cryptocurrency is too risky to use. By taking basic security precautions — controlling your own keys, using hardware wallets, and practicing good operational security — you can significantly reduce your risk while participating in the crypto economy. Security is a journey, not a destination, and every step you take makes your assets that much harder to steal.

this should be pinned everywhere for newcomers. the not your keys not your coins lesson keeps getting taught and people keep ignoring it
the guide mentions hardware wallets but honestly even a basic multisig setup would have prevented most of the loss patterns we see with exchange hacks
Lykke said they would use capital reserves to cover the $22M. anyone know if users actually got made whole or is this still dragging on?
partial refunds from what i heard. some users still waiting months later. classic exchange playbook, promise everything then deliver slowly
partial refunds after months is basically a forced withdrawal limit dressed up as generosity. 158 BTC doesnt just disappear without systemic failures
forced withdrawal limits disguised as recovery efforts is the most exchange-brained response possible. happens every single time
heard partial refunds came through for some but not all. small accounts got priority PR coverage, large accounts got silence
lykke was a small exchange too. imagine if a top 10 got hit for 22M in BTC. the damage would be 10x worse
multisig on a hardware wallet is the answer but try explaining that to someone who just wants to buy $200 of BTC on an app
