One of the most frequent worries of investors is how to keep cryptocurrency safe. In the same way that people keep cash in banks, it’s critical to protect cryptocurrencies as much as possible. Investors should be aware of the potential risks of theft, fraud, and asset loss due to the distinctive characteristics of cryptocurrencies, including how they are stored and exchanged on Internet platforms. Although safeguarding these digital assets presents certain difficulties, there are several recommended practices that can help you keep your digital cash secure.
What is a Crypto Wallet?
A cryptocurrency wallet is a digital location where you can keep your virtual money. It protects your private keys—secret credentials that enable you to access and control your cryptocurrency assets—from cybercriminals. Hot wallets and cold wallets are the two primary categories of wallets. Consider security, ease of usage, and convenience while selecting a wallet. Seek out wallets with features like backup choices and multi-factor authentication. Additionally, keep in mind not to keep all of your cryptocurrency in one wallet. For further security, distribute your holdings among several wallets. You may feel secure knowing that your digital assets are protected when you have a secure wallet.
Tips for Protecting Your Digital Currency
1. Use strong, complex, long passwords
Your first layer of protection should be a strong password. It should be lengthy (at least 14 characters), distinct, and comprise a variety of symbols, numbers, and letters. Don’t use information that can be guessed, such as birthdays or everyday terms. Hackers typically attempt to brute-force passwords using one of two methods: a “simple” attack or a dictionary attack. Dictionary attacks limit the number of possible sequences and increase the likelihood of guessing by using lists of popular passwords and patterns to try just the most frequently used combinations. Simple assaults just attempt every conceivable combination, and as the password’s length and complexity increase, so does the effort and time required to guess it. It takes years or maybe thousands of years to create long, complicated, and unpredictable passwords.
2. Store Offline When Possible
An article on the CoinTelegraph.com website states that if you are a digital currency investor who wants to make a quick trade, keeping your cryptocurrency in cold storage may make it a little more difficult to access, but most digital currency owners would argue that it is worth the security to do so because it eliminates some of the potential danger. Digital currency owners typically store their currency as a key with passwords in a digital wallet, frequently on a mobile device. Since these forms of storage are still technically online, there are inherent risks that can be addressed by moving cryptocurrency offline, a practice known as “cold storage.”
3. Use Two-Factor Authentication
It is advised that you use wallets and platforms that require at least two-factor authentication; in many cases, the first authorization would be entering a password, just like with any other login, and the second mode of authentication would be a second password sent to your smartphone, for example. While they may not be as common, physical authentication, like a fingerprint or facial/vocal recognition, would be ideal for multi-factor authentication to help keep your digital currency safe because it would be difficult for someone to obtain your digital currencies by breaking through facial recognition software.
4. Be Cautious on Mobile Devices
Cryptocurrency investors can get in touch with their phone provider and establish restrictions that might stop hackers from intercepting crucial data because many two-factor authentications use smartphones, whether it be by sending a code or an alert. To further secure your digital currency from scammers, an article on Bitcoinist.com advises you to tell your cell phone provider to never port your phone. To reduce the possibility of your phone number and information being stolen (or intercepted), you can even implement a rule that would prohibit call forwarding.
4. Encrypt Data
One useful strategy to keep your cryptocurrency safe and secure is to encrypt the devices and wallets you use. Depending on the kind of device you use, you can use a variety of data encryption programs. Another strategy to lower risk is to back up your digital assets. To make your cryptocurrencies as safe as possible, the backup drives should be encrypted.
4. Use a VPN to protect your traffic data
By encrypting your internet connection, a virtual private network (VPN) hides your IP address and makes it more difficult for hackers to track your online activity. Using a VPN protects your data and makes it less vulnerable to interception when you manage your cryptocurrency assets or do transactions. Selecting a trustworthy VPN provider with a solid track record is important, though; stay away from companies that have already experienced hacking.
5. Be Aware and Complete Due Diligence
Even though malicious actors frequently try to carry out phishing attempts, take precautions to avoid becoming one of the possible victims. Be careful when opening emails, pay attention to links on websites, and avoid entering personal information anywhere that can be unsafe. To protect your data, try to come up with strong, hard-to-crack passwords for your phone number, email address, credit card, and cryptocurrency wallet. Someone may be one step closer to hacking your cryptocurrencies if they are able to obtain some of your personal data.
Doing due diligence on the platforms and wallets you use to protect your digital assets can be beneficial in addition to just being mindful of what you’re doing online. Buying and trading cryptocurrencies increases the likelihood that other users could obtain your funds and private data without your knowledge or consent. You can avoid theft and trade with confidence if you use a digital currency platform with additional security safeguards and defensive features. To possibly prevent theft or problems, carefully examine the credentials and security features of a wallet or trading platform before choosing one.
Public and private key of crypto wallets
Crypto wallets have at the heart of their mechanism two components: private and public keys. The public key acts as an address that others can use to send you cryptocurrency. Think of it as your bank account number, which is publicly visible and necessary for receiving funds. The private key, on the other hand, is your secret password. It’s the only thing that can authorize the transfer of your funds, making it the most crucial element in crypto security. If someone gains access to your private key, they gain full control over your assets.
Types of crypto wallets
Wallets can be broadly categorized into hot and cold wallets.
1. Hot wallets
Hot wallets are cryptocurrency wallets that are linked to the internet, which increases their accessibility for trading and everyday transactions but also leaves them open to hacking and other dangers. We strongly advise against putting your long-term assets in online wallets like Metamask or Phantom or using hot wallets like exchange wallets for anything other than trading and everyday transactions. Since hackers can execute transactions by brute-forcing the wallet’s password without needing the precise seed phrase or private key, hot wallets are comparatively simple to steal if they infect your machine with a virus. Brute-forcing a password is far simpler than brute-forcing a seed phrase, and thus increases the vulnerability of hot wallets. Convenience and ease of use are a hot wallet’s main advantages, however, compared to cold wallets, which are offline storage options, there is a greater chance of security breaches.
2. Cold wallets
Cold wallets are a kind of cryptocurrency wallet that is not online and typically take the kind of tangible hardware devices like Trezor or Ledger. Because an attacker may only access your cold wallet by learning your seed phrase to conduct transactions, this offline condition greatly increases its security against online attacks, hacking, and other digital risks. Unlike hot wallets, it is probably difficult for the fraudster to access your wallet if you only save the seed phrase offline on a metal card that is maintained in a secure location. As you can see, cold wallets are intended to safely store greater amounts of cryptocurrency or assets that you don’t need to access right away. However, in comparison to hot wallets, they may not be as practical for frequent transactions.
What is a seed phrase?
The password to unlock the wallet is a string of 12 or 24 random phrases. You must keep it safely in a private location, ideally on a metal card, as it is the only method to access it. It’s crucial to keep your seed phrase safe since once you lose it, you won’t be able to get your cryptocurrency back. Can an automated script be used to brute-force a seed phrase by attempting every conceivable combination? Of course not, it’s probably not feasible because it would take a tremendous amount of time and computational energy—guessing a 12-word seed phrase would involve attempting 2048^12 combinations—and it would take decades at the very least.
Most Common Threats to Crypto Wallets
You can have some piece of mind by putting the best security measures mentioned above into place, but keep in mind that scammers are constantly investing in new ways to trick people using a variety of strategies.
1. Phishing attacks and social engineering
The most popular strategy is phishing attacks, in which con artists pose as reliable organizations in an effort to steal private keys or login credentials. To fool you into giving them your private key or seed phrase, they essentially copy emails, websites, or links from ostensibly legitimate relevant sources, like cryptocurrency exchanges, wallet providers, and financial authorities. Your seed phrase and private key should never be shared.
2. Malware and ransomware
Scammers use malicious software to encrypt files or compromise a device in order to extort a ransom. Malware such as keyloggers can record login credentials or private keys. Install a safe antivirus program on your PC and stay away from dubious links and websites. Keep an eye out for direct messages from strangers and be on guard at all times.
3. Scams and fraud
Scammers sometimes employ phony initial coin offerings (ICOs), investment scams, and ponzi schemes to defraud people of their cryptocurrency assets. Before making any purchases, always confirm the legitimacy of projects and people and look for any potential red flags. Never make snap decisions and always do your homework.
4. Weak passwords
Weak or simple passwords for wallet access or related email accounts are more likely to allow unauthorized access. If you use an exchange wallet, for instance, a fraudster may use your email password to get a new password for the crypto wallet, which would allow them access to your cryptocurrency as well. For each account connected to your cryptocurrency holdings, including the mail, create a strong, one-of-a-kind password. Make your password complex by including numbers, unusual characters, and a lengthy password.
5. Unsecure networks
Steer clear of public or unprotected WiFi networks as they may reveal your wallet details to scammers or possible interceptors. Hackers frequently infect public Wi-Fi networks with harmful software and wait for the ideal victim to take their cryptocurrency assets. Avoid public WiFi at all costs and always use a VPN to secure your traffic data.
The Importance of Cryptocurrency Security
Security is crucial when it comes to digital currency. In contrast to traditional financial systems, where a central authority may be able to reverse fraudulent transactions, cryptocurrencies use blockchain technology, which records transactions on numerous computers and renders them irreversible. This implies that a security error could result in irreversible loss. In the history of cryptocurrencies, there have been numerous security lapses that have resulted in the theft of substantial sums of digital assets.
For example, 740,000 bitcoins, or billions of dollars in today’s currency, were lost in the notorious Mt. Gox breach in 2014. More recently, in 2021, a significant hack occurred on the DeFi platform Poly Network, resulting in a loss of more than $600 million. These occurrences demonstrate how crucial robust security measures are to preserving public confidence in the cryptocurrency market. Therefore, it’s critical that everyone in the crypto industry employs robust security procedures.
Conclusion about Cryptocurrency Safe
Cryptocurrency security is paramount to protect your digital assets from risks like theft, fraud, and loss. Using a secure wallet, practicing due diligence, and following best practices such as strong passwords, cold storage, two-factor authentication, and VPNs can significantly enhance your crypto safety. Understanding the functions of public and private keys, seed phrases, and the distinctions between hot and cold wallets is crucial for informed decision-making.
Staying vigilant against phishing attacks, malware, and scams ensures further protection. Ultimately, safeguarding cryptocurrencies is not only about technology but also about consistently implementing robust and mindful security practices.
