How to Keep Your Crypto Secure? 10 Tips to Secure Crypto Wallets

How to keep your crypto secure is one of the most important questions any trader or investor can ask. With crypto scams, exchange hacks, and wallet thefts continuing to rise, even a small mistake can lead to serious financial loss.

In this article, I explain 10 practical ways to protect your cryptocurrencies, avoid common crypto scams, and build safer habits as you trade. Whether you hold a modest amount or manage significant digital assets, these tips will help you keep safety top of mind and reduce unnecessary risk.

What are the best ways to secure your cryptocurrencies?

1. Use a cold wallet

I hear a lot of people ask "what is a crypto wallet in the first place?" A crypto wallet is an online or offline storage facility that acts like a physical wallet, except it keeps the private keys to your cryptocurrencies safe. A crypto key is a very long number that is used in cryptography. It acts like a password. The bottom line is that whoever is in possession of the keys is in possession of the crypto coins.

For obvious reasons, private keys must be stored safely. Hot wallets are crypto wallets that are connected to the internet, but these are subject to hacking. In 2022, crypto exchange FTX was hacked shortly after filing for bankruptcy, resulting in the theft of more than $470 million in cryptocurrency from customer accounts.

Cold wallets are not connected to the Internet and are, therefore, less likely to be compromised. Cold wallets come in a USB-like device that you can store securely, for example, in a safe. Cold wallets are also known as offline or hardware wallets. Using a cold wallet is one of the safest ways to store your private keys.

2. Use a secure internet connection

I recommend that new crypto traders never process transactions over an unsafe Internet connection. Thankfully, the average person knows better than to make sensitive financial transactions over an unsafe network in an internet café. The same applies to crypto investing. Public Wi-Fi networks are not safe and can often be exploited by threat actors to gain access to crypto private keys and crypto exchange passwords. Even if your crypto investments are on a bear run and you must urgently place an order, resist the urge to use public connections.

Sometimes, traders make use of office or school Internet connections. After all, most crypto traders pursue their crypto trading careers while working full-time or studying. Although most organizations like these have firewalls and antivirus protection, they could still expose you. It is best practice to use a VPN for additional security. One recurring pattern I’ve noticed during periods of high market volatility is that traders are more likely to ignore connection security when rushing to place orders, which is exactly when avoidable mistakes tend to happen.

3. Keep multiple wallets

Just as you must diversify your investments in general, the same goes for keeping your cryptos safe. Keeping your private keys stored on multiple wallets significantly reduces your chances of suffering a catastrophic loss. It is much more likely for only one of your wallets to be compromised rather than all of them. Use more than one cold wallet for long-term storage and at least one hot wallet with fewer funds for daily transactions.

4. Strengthen your device safety

Crypto traders can just as easily work from their mobile phones, laptops, or desktops. This variety of devices is what makes trading in today’s world so convenient. However, the downside is that it leaves you exposed to cyberattacks.

Many people go to the trouble of securing laptops and desktops, but fewer people remember to secure their mobile phones. You should always install antivirus software with the newest virus definitions to protect you from newly discovered vulnerabilities.

How often should you update your crypto password?

You should update your crypto password regularly and make sure it stays strong and hard to guess. Good password management matters because cyber criminals use increasingly powerful tools to steal weak credentials. Treat your crypto wallet or crypto exchange password with the same care as your internet banking login.

How can you avoid phishing scams in crypto?

You can avoid phishing scams in crypto by staying alert to malicious emails, advertisements, and links that try to expose you to theft. Basic phishing uses deceptive messages to get you to click, while spear-phishing goes further by impersonating trusted contacts or using fake domains. Watching for these malicious links helps protect your wallet and accounts.

A popular scam in crypto and online trading uses fake Websites that look like real crypto exchanges to steal account information. You should always double-check the Web address before you log into your account or enter any of your details.

Should you entrust your crypto wallet to someone else?

You should be cautious about entrusting your crypto wallet to someone else because it means another party may control your private keys. Some providers offer this arrangement through a custodial wallet, which handles key security on your behalf. That is the opposite of a non-custodial wallet, where you remain responsible for your own wallet.

Custodial wallets reduce your responsibility for safeguarding keys, but they are more dangerous because a third party holds your private keys. This is often a trusted crypto exchange, but it can still be hacked, and you may not be compensated for lost funds. With a non-custodial wallet, you have total control of your private keys and your funds. Some people feel safer with this type of wallet, which can be browser-based or hardware-based.

Why should you back up your crypto wallet?

You should back up your crypto wallet because regular backups may be the only way to recover your funds if you lose your device. If your private keys are lost, your assets can be lost as well. Depending on the wallet's security settings, failed attempts to guess signatures may cause the wallet to lock and encrypt its content entirely.

9. Update your software I wasn't very good at this in the beginning, but after missing several wallet and device updates over a period of months, I started treating them like part of my regular trading routine rather than an afterthought. With crypto, a wallet running on old software can be an easy target for cybercriminals. Each iteration of wallet software contains improved security against known weaknesses. It may be a pain to remember, especially during the thrill of trading, but it is one of the best ways to keep your assets safe.

What is a multi-signature wallet, and should you use one?

A multi-signature wallet is a wallet that requires at least two signatures before it can be opened, and it can add meaningful security for some users. These wallets can be configured to require approval from several people before access is granted. Although this setup can feel cumbersome, it may better protect your crypto assets over the long run.

5. Update your password regularly

In this modern age, password management is an important practice. Be sure to implement only the toughest and most complicated passwords possible. Also, change your password regularly. With increasingly powerful password-hacking software, it is becoming easier for cyber criminals to steal passwords.

Think of your crypto wallet in the same way as you would your Internet banking password. You would not use a password that is easy to guess for your mobile banking app, so you should apply the same importance to your crypto wallet or crypto exchange password.

6. Be aware of phishing

Phishing scams are on the rise, as mentioned repeatedly by the FTC and other financial watchdogs. Phishing is when malicious advertisements and emails entice you to click on a link that exposes you to theft. Spear-phishing is when criminals go one step further and use fake domains impersonating known contacts with which you have had dealings to get you to click malicious links.

In what is now a popular scam in the crypto world and in online trading in general, criminals engineer fake Websites that look like real crypto exchanges but are actually trojan horses designed to steal account information. You should always double-check the Web address before you log into your account or enter any of your details.

7. Be careful of entrusting wallets to others

Care should be taken when you decide to entrust your crypto wallet to someone else. Some providers offer to take the hassle out of keeping your private keys safe by giving you the option to entrust your wallet to them. This is known as a custodial wallet.

It is the opposite of a non-custodial wallet, which is when you oversee keeping your own wallet.

Custodial wallets give you the benefit of having less responsibility for safeguarding your valuable keys, but it is thought to be much more dangerous because you are placing your private keys in the hands of a third party. Granted, this is often a trusted crypto exchange, but even they can be hacked, and since no crypto exchange is currently compelled to compensate you for lost funds, you are placing yourself at risk. With a non-custodial wallet, you have total control of your private keys and your funds. Some people feel safer with this type of wallet, which can be browser-based or hardware-based.

8. Backup your wallet

You should get into the habit of performing backups of your crypto wallet as often as you can. If you lose your trading device but you have a trail of regular backups, this may be the only way to recover your currency from a digital wallet. If you lose your private keys, you lose your funds. It is that simple. Depending on the security settings of the wallet, if you unsuccessfully try to guess the signatures, the crypto wallet will lock itself and encrypt its content entirely.

Why should you keep your crypto software updated?

I wasn't very good at this in the beginning, but I now know that anyone with a digital signature should know to keep their software up to date. With crypto, a wallet running on old software can be an easy target for cybercriminals. Each iteration of wallet software contains improved security against known weaknesses. It may be a pain to remember to do this, especially during the thrill of trading, but it is one of the best ways to keep your assets safe and is housekeeping you must carry out as part of your crypto trading risk management and trading strategy.

10. Use a multi-signature wallet

Multi-signature wallets can be customized to match your security needs, allowing you to set the number of required approvals beyond the minimum of two signatures.
