Cryptocurrency wallets are digital tools that allow you securely to store and manage your cryptoassets. There are various types of cryptocurrency wallets, each with unique features and benefits, including hot wallets and cold wallets. In this guide, we’ll explore the different types of wallets available, their pros and cons, and tips to keep your cryptoassets protected. 


Researching the crypto market and identifying trading opportunities are important to successfully invest in cryptocurrency. But one of the most important aspects of owning crypto is storing them in a safe and secure place

This is where a cryptocurrency wallet comes into play. 

Consider a traditional wallet you use to store your cash and credit cards. You keep these valuables safe by keeping them in one place. It’s the same for your cryptocurrency transaction records that are stored on the blockchain.

A cryptocurrency wallet is similar. It’s a digital tool used to store, send, and receive digital assets such as Bitcoin, Ethereum and others.

In this beginner’s guide, we’ll dive into the world of digital wallets, exploring the types available, how they work, and how you can keep your digital assets safe.

What is a cryptocurrency wallet?

A crypto wallet hardware or software that interacts with blockchains and lets you store or trade digital assets, such as Bitcoin, Ethereum, or any other type of cryptocurrency. 

With a cryptocurrency wallet, you can manage your digital assets, send and receive crypto, monitor your real-time transactions, and keep your digital currency safe. 

Tip: Many crypto wallets also provide oversight of your investments and the market through dashboards with monitoring and reporting tools.

Cryptocurrency wallets don’t actually hold your cryptocurrency like a traditional bank account. Instead, it stores your private keys that are used to access your cryptocurrency transactions. 

These keys are essentially a long string of numbers and letters that act as your digital signature. Without them, you cannot access your funds.

There are two main types of cryptocurrency wallets. 

  • Hot wallets. These are pieces of software, connected to the internet, that help you buy, sell and store your investments. They are often considered more convenient, but less secure.
  • Cold or hardware wallets. These are offline wallets, a physical  object, that help you keep your cryptocurrency safe. They offer the highest level of security, but require additional steps to access your funds. 

We will discuss the benefits of each type of wallet later in this article.

Crypto wallets can also be classified based on the types of digital currency they can send and receive. To buy and sell Bitcoin, you will need a Bitcoin wallet or a wallet compatible with that type of currency. The same goes for an Ethereum wallet, and so on.

Many wallets offer additional features such as the ability to exchange between different cryptocurrencies or even earn interest on your digital assets. 

How do cryptocurrency wallets work?

Cryptocurrency wallets are essential for anyone who wants to buy, own, or sell crypto.  Your wallet stores your private and public keys and interacts with different blockchains to allow you to securely send and receive digital assets.

All crypto wallets work using the same principles via tools called keys. But, just as your crypto wallet isn’t a  physical wallet, these are not physical keys that you carry around, either.

The keys in your wallet are used to facilitate transactions and keep the crypto in your wallet secure. Each wallet has a public address, a public key and a private key

What is a public address?

A public address is a unique identifier used to receive cryptocurrency. Think of it as the destination address for your digital assets. 

When you buy cryptocurrency, the seller sends a record of ownership to your public address. When someone wants to send you crypto, they use your public address to send it to you. 

As the name suggests, this address is public and can be shared with anyone without compromising the security of your crypto. 

What is a public key?

A public key verifies you’re the owner of a public address that can send and receive cryptocurrency.

It’s  a long string of  letters and numbers. An example of a public key could be: X8asDFk76z9T100zrU79xbM777. 

Public keys can be used to encrypt messages that are sent to your public address, ensuring that only the intended recipient can read them. 

They’re matched to the private key held within the crypto wallet, but unlike traditional banking details, these keys don’t provide any personal information about the wallet’s owner. This means you can share your public key without risking security

What is a private key?

A private key acts as the password for cryptocurrency wallets. It’s a secret code that allows you to access and transfer your cryptocurrency. 

Your private key is linked to your public key and is necessary to verify any transactions on the blockchain.  It’s like the password to your online bank account. It is the key piece to your cryptocurrency security — never share or give this key to anyone.

Anyone using a cryptocurrency wallet needs to take precautions to protect their assets, including creating secure passwords, regularly backing up wallet data, enabling two-factor authentication, and keeping your private keys in a secure location.

What types of crypto wallets are available?

As mentioned above, there are two main types of wallets: hot wallets and cold wallets. 

When it comes to choosing a wallet, it depends on your individual needs and preferences. If you plan on frequent trading and transactions, a hot wallet may be more suitable for you. If you’re looking for more security for your long-term holdings, a cold wallet is the way to go.

Hot wallets

Hot wallets are connected to the internet, making them convenient and easy to access. They’re often used for frequent trading and transactions, as they allow for quick and easy access to funds. 

But because they’re connected to the internet, hot wallets are more vulnerable to hacking and theft. It’s important to only keep a small amount of funds in your hot wallet at any given time.

There are different types of hot wallets, including desktop wallets, mobile wallets, and online wallets. 

  • Desktop wallets are installed on a user’s computer and can only be accessed there, limiting your access – and hackers’ access – to your funds.  While desktop wallets offer a higher degree of security than other hot wallets, they are still vulnerable to cyber attack.
  • Mobile wallets are downloaded on your phone and provide easy access to your funds, making them ideal for traders who regularly buy, sell, and access their cryptocurrency. While there are still security threats, fingerprint and face ID technology in today’s mobile devices can help make mobile wallets safer. 
  • Online wallets are accessed through a web browser and offer a high degree of convenience, as they can be accessed from anywhere in the world with an internet connection, but are considered less secure than other wallets .

Cold wallets

Cryptocurrency hardware wallets, or cold wallets, are physical tools for keeping crypto. They’re not connected to the internet, making them far more secure than hot wallets – and ideal for long-term storage. 

Cold wallets can come in the form of hardware devices, such as USB sticks or specialized devices like Trezor and Ledger, or even as pieces of paper with codes that contain proof of crypto ownership. 

Cold wallets are perfect for those who trade less often, and who want maximum security for their cryptocurrency holdings.

The physical nature of these wallets can make them more secure because they are less likely to be accessed online by hackers.

Of course, cold wallets  can still be stolen or lost, and you can forget how to access them. Many people put their hardware wallets in a safe deposit box at a bank or other secure location.

How do I decide which wallet to use?

Deciding which type of wallet to use depends on a variety of factors, including:

  • How often you trade. If you’re an active trader who makes daily transactions, you’ll need a wallet with fast processing times and low fees. A hot wallet would be better, as it allows for instant transactions and easy access of your funds  Cold wallets are better suited for those looking to make less frequent trades.
  • What you want to trade. Different wallets support different cryptocurrencies, so it’s essential to choose a wallet that supports the specific assets you want to trade. If you’re looking to trade lesser-known cryptocurrencies, you’ll need a wallet that supports a wide range of assets, preferably a multi-currency wallet.
  • Your peace of mind. If you’re worried about hacking, having a physical cold wallet, stored in a safe deposit box at the bank or somewhere at home, provides the safest, most secure option. Others may be confident in their ability to keep their hot wallets secure in exchange for the convenience
  • How much it costs. While some hot wallets are free, others come with subscription fees. Most cold wallets, like other types of hardware, cost a one-time fee. Look out for transaction fees, which may vary by wallet. For instance, some cold wallets charge higher fees compared to others. 
  • What it can do. While the basics of each cryptocurrency wallet are the same, additional features can help set them apart. Hot wallets especially come with varying features, ranging from staking to lending capabilities, and decentralized finance functions. If you are an active trader who wants to dabble in DeFi or stake your assets, you may require a hot wallet with advanced functionality.  

5 tips for keeping your crypto wallet secure

Even if you have the best wallet on the market, it’s  not going to matter if you don’t keep your wallet secure. Here are some tips to keep your wallet safe:

  • Keep your private key private. This is the most important part of securing your wallet, as it’s essentially the key that unlocks access to all of your digital assets. Never share your private key with anyone, and always use two-factor authentication whenever possible. 
  • Keep your cold wallet secure. Make sure to keep your cold wallet in a safe place, like a locked drawer or safe. 
  • Have a backup plan. This could mean keeping a copy of your private key in a secure location, or setting up automatic backups of your wallet data. That way, if anything goes wrong with your main wallet, you’ll still be able to access your assets. 
  • Don’t get phished. One way that people fall victim to crypto theft is through phishing scams. These are usually emails or messages that look like they’re from a legitimate company or organization, but are actually fake. The goal of these scams is to get you to share your private key or other sensitive information, which the scammers will then use to access your assets. To avoid falling for a phishing scam, always double-check the source of any message or email before responding, and never share your private key with anyone.
  • Mind the network.  Be careful about which networks you connect to when accessing your wallet. Make sure to only use trusted networks, and to always verify the authenticity of any new connections before allowing access to your wallet.
