Hot wallets: features, security, and use cases
What are hot wallets?
Hot wallets are cryptocurrency wallets that stay connected to the internet, making them perfect for quick and easy transactions. These wallets, which are software-based, can be accessed through mobile apps, web platforms, or desktop programs, giving users instant access to their digital assets.

Hot wallets store private keys digitally, allowing users to securely sign and verify blockchain transactions. They come in two main types: custodial and non-custodial. Non-custodial wallets are particularly appealing because they give users complete control over their private keys.
Main advantages of hot wallets
The standout advantage of hot wallets is their convenience. They make it easy to store, receive, send, and monitor cryptocurrency in real time, which is why they are a favorite among active crypto users.
Hot wallets also integrate seamlessly with decentralized applications (dApps) and DeFi platforms. This makes them ideal for activities like staking, participating in liquidity pools, and other blockchain-based financial services. On top of that, most hot wallets are free or come with minimal costs, making them especially attractive to beginners. Their intuitive interfaces simplify asset management and make blockchain interactions more accessible.
Security risks of hot wallets
The constant internet connection that makes hot wallets convenient also makes them vulnerable to security threats. Hackers often target these wallets, using methods like phishing attacks, malware, and direct hacks. In 2024, private key breaches accounted for 43.8% of all cryptocurrency thefts, highlighting the risks associated with hot wallets.
A striking example of this occurred in July 2024, when the Indian cryptocurrency exchange WazirX was hacked. Attackers manipulated transaction data, resulting in the theft of over $234 million in crypto assets. The stolen funds included $11,166,889.57 in MATIC, $97,264,169.13 in SHIBA, and $52,975,393.96 in ETH.
Software vulnerabilities add another layer of risk. Outdated software, weak passwords, and poor coding practices can create openings for cybercriminals to exploit.
When to use hot wallets
Hot wallets shine in situations where speed and convenience are essential. If you’re someone who frequently trades, spends, or transfers cryptocurrency, the instant access these wallets provide can be a game-changer. Active traders, in particular, benefit from the ability to quickly react to market changes. Additionally, hot wallets are ideal for engaging with dApps, staking platforms, or liquidity pools.
For beginners, hot wallets are a great starting point. They offer a simple way to learn about digital transactions and explore decentralized applications without the added complexity of hardware wallets.
That said, hot wallets are best suited for daily transactions or smaller amounts. For larger holdings or long-term storage, transferring funds to a more secure option is advisable. Up next, we’ll explore cold wallets, which take a different approach to safeguarding digital assets.
Cold wallets: features, security, and use cases
What are cold wallets?
Cold wallets are devices designed to store cryptocurrency private keys completely offline, shielding them from internet-based threats like hacking or malware. Unlike hot wallets, which trade some security for convenience, cold wallets focus on keeping your keys safe by ensuring they remain disconnected from online networks.
Cold wallets come in a few forms, each with its own approach to security. Hardware wallets - small devices resembling USB drives - are among the most popular. Air-gapped devices take things further by never connecting to the internet at all, while paper wallets involve printing or writing your private keys on physical paper.
This offline storage method is what makes cold wallets stand out. It’s their defining feature and the reason they’re so effective at protecting your assets, as we’ll explore below.
Benefits of cold wallets
The biggest advantage of cold wallets is their robust protection against online threats. Whether it’s hacking, malware, or phishing schemes, cold wallets minimize these risks by keeping your private keys offline. This level of security is critical, especially when you consider that hackers have stolen over $7 billion in cryptocurrency since 2022, with most of these losses tied to compromised private keys.
Unlike hot wallets, which are susceptible to software vulnerabilities and network attacks, cold wallets significantly reduce the potential points of failure by operating offline.
For long-term investors, cold wallets are a reliable option. Properly maintained, these devices can last 5 to 10 years, making them perfect for holding onto assets through market fluctuations. They also allow you to retain full ownership of your private keys, giving you complete control over your funds without relying on third-party custodians.
Drawbacks of cold wallets
While cold wallets excel in security, they require some sacrifices in convenience. Accessing your funds involves extra steps, like physically connecting a device or retrieving a paper wallet, which makes them less practical for frequent trading.
Cost is another consideration. Unlike hot wallets, which are often free, hardware wallets typically range from $50 to $200 - a potential barrier for newcomers .
Physical risks are also a concern. Cold wallets can be lost, damaged, or even destroyed by events like fires or floods. Without a properly backed-up seed phrase, losing your wallet could mean losing access to your cryptocurrency forever. Some estimates suggest that as much as 20% of all Bitcoin in circulation may be stranded due to such losses.
Finally, there’s a learning curve. Cold wallets require you to understand concepts like seed phrases, private key management, and secure backups. Unlike the user-friendly interfaces of hot wallets, cold wallets demand a bit more technical know-how to use safely.
When to use cold wallets
Cold wallets are ideal for long-term storage, especially when dealing with significant amounts of cryptocurrency that you don’t plan to trade often. While hot wallets are better suited for everyday transactions, cold wallets shine when security is the priority. They’re particularly valuable for those holding Bitcoin or other cryptocurrencies as a long-term investment .
For high-value holdings, the added inconvenience of offline storage is a small price to pay for the enhanced security. Many investors adopt a hybrid approach, keeping small amounts in hot wallets for daily use while storing the bulk of their assets in cold wallets. This strategy works well for retirement savings, inheritance plans, or any situation where funds are meant to remain untouched for years.
Businesses and institutional investors often turn to cold wallets for managing large reserves, where security takes precedence over quick access. Many cold wallet solutions also support multi-signature features, which add an extra layer of security and governance.
If you’ve faced security issues with hot wallets or operate in a high-risk environment, cold wallets are an essential tool for safeguarding your assets. They provide the peace of mind that comes with knowing your cryptocurrency is protected by one of the most secure storage methods available.

Security comparison table
Choosing the right wallet for your cryptocurrency comes down to how well it secures your private keys - arguably the most critical factor. The table below lays out a side-by-side comparison of hot and cold wallets, helping you evaluate which one suits your needs best.
| Feature | Hot Wallets | Cold Wallets |
|---|---|---|
| Internet Connectivity | Always online | Offline (can integrate with hot wallets) |
| Security Level | Lower – vulnerable to online attacks | Higher – immune to online threats |

| Best For | Smaller amounts, daily transactions | Large amounts, long-term storage |
| Access Speed | Instant access | Takes multiple steps to access funds |
| Vulnerability | Susceptible to hacking, malware, phishing | Protected by secure chips, PINs |
| Private Key Storage | Stored on internet-connected devices | Stored on secure chips, inaccessible even with physical access |
The difference in security between these two wallet types is substantial. Hot wallets, being online, are more exposed to risks like hacking or phishing. On the other hand, cold wallets store private keys on secure hardware chips, making them almost impossible to compromise - even if someone physically accesses the device.
Given the history of cryptocurrency theft, these distinctions are crucial. The table provides a clear overview to help you pick the wallet type that aligns with your priorities.
Which wallet type is safer for you?
Your choice between hot and cold wallets largely depends on how you use your cryptocurrency. If you're an active trader, a hot wallet might be more practical due to its instant access and compatibility with exchanges and DeFi platforms. However, storing only the amount needed for daily use in a hot wallet is a smart way to limit potential losses in case of a breach.
For long-term investors, cold wallets are the safer bet. They offer features like Secure Element chips that safeguard against tampering and brute-force attacks. Some even include air-gapped technology, ensuring they never connect to the internet, which adds an extra layer of protection.
Many experienced users adopt a hybrid strategy: keeping a small amount in a hot wallet for daily transactions while securing the bulk of their holdings in a cold wallet. This approach strikes a balance between convenience and security, making it possible to trade actively without compromising long-term safety.
Ultimately, your decision hinges on what matters most to you: ease of access or maximum security. For those holding large sums or investing for the long term, the added steps of using a cold wallet are well worth the peace of mind they provide.

Best practices for securing digital wallets
Security tips for all wallets
Whether you're using a hot wallet or a cold wallet, some security measures are universal. These steps are essential for protecting your cryptocurrency and keeping cybercriminals at bay.
Create a strong password. Your wallet password should be at least 14 characters long and include a mix of uppercase letters, lowercase letters, numbers, and symbols. Avoid using easily guessed information like birthdays or names. A strong password is your first defense against unauthorized access.
Use two-factor authentication (2FA). Adding 2FA creates an extra layer of security for your wallet. Instead of relying on SMS-based 2FA, which can be intercepted, opt for authenticator apps like Google Authenticator or Authy. This ensures that even if your password is compromised, your wallet remains protected.
Safeguard your seed phrase. The seed phrase is the key to your wallet, granting full access to your funds. Store it offline, such as on a metal card, and keep it in a secure and private location. Never share it with anyone.
Keep your software up to date. Regular updates for your wallet app, operating system, and antivirus software are crucial. These updates fix known vulnerabilities that hackers might exploit. Staying current significantly reduces your risk of being targeted.
Be cautious of phishing scams and social engineering. Always double-check the legitimacy of websites and communications before entering sensitive information. Cybercriminals often use fake websites or emails to trick users, so vigilance is key.
Monitor your wallet activity. Regularly review your wallet balances and transaction history for any unauthorized activity. Early detection can help you act quickly to mitigate potential losses. Many wallet providers offer alerts, which can add an extra layer of security.
Use a VPN on public WiFi. Public WiFi networks are notoriously insecure. A VPN encrypts your internet connection, protecting your data from potential snoopers. Avoid accessing your wallet or making transactions on unsecured networks.
Adopt a multi-wallet strategy. For better security, use a cold wallet to store large amounts of cryptocurrency and a hot wallet for smaller, daily transactions. This way, even if your hot wallet is compromised, the majority of your assets remain safe. Additionally, if you're using a hot wallet, disconnect it from decentralized applications (dApps) and third-party sites after use.

Conclusion: Choosing the Right Wallet for Your Needs
Deciding between a hot wallet and a cold wallet comes down to balancing convenience and security. Hot wallets provide instant access and are easy to use, making them a go-to choice for active traders who need quick transactions. However, they come with the risk of online threats.
Cold wallets, on the other hand, are designed for long-term storage. By keeping your funds offline, they offer stronger protection against cyber risks. The downside? They’re less convenient, often requiring extra steps to access your funds and sometimes involving upfront costs for hardware.
"Think of hot wallets as checking accounts - easy to use but riskier. Cold wallets are like safety deposit boxes - less convenient but more secure."
- Fei Chen, founder and CEO, Intellectia
Your choice should reflect your trading habits, risk tolerance, and the size of your investment. If you trade frequently and need fast access, a hot wallet might be the better fit, despite its vulnerabilities. For those with significant holdings intended for the long haul, a cold wallet provides the security you need. Many cryptocurrency users find a middle ground by using both: keeping smaller amounts in hot wallets for daily use while safeguarding the bulk of their assets in cold wallets.
Equally important is selecting a secure platform for purchasing cryptocurrency. Services like Kryptonim offer a regulated, account-free option to safely transfer funds to your chosen wallet. No matter which type of wallet you use, strong security practices are essential.
