What Is a Bitcoin Wallet?

A Bitcoin wallet is a digital tool that allows users to securely store, send, and receive Bitcoin, the world’s most popular cryptocurrency. Essentially, it is a software programme that interacts with the Bitcoin blockchain, enabling users to manage their Bitcoin holdings. Unlike traditional wallets that hold physical currency, Bitcoin wallets store a user’s private and public keys, which are essential for conducting transactions on the blockchain.

In general, wallets that store Bitcoin also store many other cryptocurrencies. Bitcoin wallets come in various forms, including software and hardware wallets

Each type has its own advantages and disadvantages, and choosing the right one depends on a user’s specific needs and preferences. Regardless of the type, all Bitcoin wallets function on the same basic principles of encryption and blockchain technology.

Different Types of Bitcoin Wallets

Software wallets (hot wallets)

These are apps that allow holders to manage their Bitcoin on the go. Known as ‘hot wallets’, since they are connected to the internet, these wallets are convenient and easy to use but carry potential risks since computer networks have hidden vulnerabilities that can be targeted by hackers or malware programmes to break into the system. A popular and secure software wallet is the DeFi Wallet.

Hardware wallets (cold wallets)

Considered the most secure option, hardware wallets store a user’s private keys offline on a physical device, offering protection against malware and hacking attempts compared to hot wallets. As these devices keep a user’s Bitcoin offline, they are considered ‘cold wallets’. Popular cold wallets include Trezor, Ledger, and KeepKey.

Custodial wallets

Typically offered on cryptocurrency exchanges, custodial wallets are known for their convenience and ease of use, and are especially popular with newcomers, as well as experienced day traders. The main difference between custodial and other wallets is that users are no longer in full control of their tokens, and the private keys needed to sign for transactions are held only by the exchange.

The implication here is that users must trust the service provider to securely store their tokens and implement strong security measures to prevent unauthorised access. These measures include two-factor authentication (2FA), email confirmation, and biometric authentication.

Reputable cryptocurrency exchanges also take further steps to ensure the safety of users’ tokens. For example, a portion of the funds is generally transferred to the company’s cold wallet, safe from online attackers.

The App is an example of a custodial cryptocurrency wallet.

Non-custodial wallets

Non-custodial wallets, on the other hand, allow a user to retain full control of their funds, since the private key is stored locally with the user.

When starting a non-custodial wallet, the user is asked to write down and safely store a list of 12 randomly generated words, known as a ‘recovery’, ‘seed’, or ‘mnemonic’ phrase. From this phrase, the user’s public and private keys can be generated. This acts as a backup or recovery mechanism in case the user loses access to their device.

A main pro of non-custodial wallets is that the private keys and funds are fully in the user’s control. As the popular saying within the crypto community goes, ‘not your keys, not your coins!’.

On the flip side, this means that users must be in charge of their own security with regard to the storage of passwords and seed phrases. Anyone with the seed phrase is able to gain full control of the funds held in that wallet. In a case scenario where the seed phrase is lost, the user also loses access to their funds.

Note that hardware wallets are inherently non-custodial, since private keys are stored on the device itself. There are also software-based non-custodial wallets, such as the DeFi Wallet.

For more on the differences between custodial and non-custodial wallets, our guide breaks it down.   

Choosing a Bitcoin Wallet

Selecting the appropriate Bitcoin wallet requires careful consideration of several factors. Below are a few key points to keep in mind:


Security should be a user’s top priority when choosing a Bitcoin wallet. Look for wallets that offer features like two-factor authentication (2FA), encryption, and backup options. Hardware wallets are generally considered the most secure option.


Consider how user-friendly the wallet is, especially for those new to Bitcoin. Look for wallets with intuitive interfaces and clear instructions for setting up and using the wallet.

Intended use

For users making frequent trades, a hot wallet is more convenient, as it stays connected to the internet. For HODLers of Bitcoin holding for the long term, a cold wallet might be the better choice to keep their cryptocurrency securely tucked away.


Research the reputation of the wallet provider to ensure it has a history of security and positive user reviews. Look for wallets that have been around for a while and have a large user base.

Bitcoin Wallet Security Measures

Security is a central factor to consider when choosing a Bitcoin wallet. Below are several measures to take into account:

Use strong passwords

Create a unique and complex password. Avoid using easily guessable passwords or reusing passwords from other accounts.

Enable two-factor authentication (2FA)

2FA adds an extra layer of security by requiring the user to provide a second verification to access their wallet, such as a fingerprint scan or a code sent to their mobile device.

Keep software up to date

Holders should regularly update their Bitcoin wallet software to ensure they have the latest security patches. Outdated software may contain vulnerabilities that can be exploited by hackers.

Back up the wallet

Create regular backups for the wallet and store them in secure locations, such as encrypted USB drives or offline storage devices. This helps ensure recovery of funds in case of theft, loss, or hardware failure.

Be cautious of phishing attempts

Users should be aware of suspicious emails, websites, or links that may try tricking them into revealing their wallet’s private keys or login credentials. Always verify the authenticity of the source before providing any sensitive information. Take a look at this list of scams to watch out for.

How to Set Up a Bitcoin Wallet

Setting up a Bitcoin wallet is a straightforward process. Below is a general guideline to get started:

  1. Choose the type of wallet: Determine which type of Bitcoin wallet adheres to your preferences like security, convenience, and intended use.
  2. Research wallet options: Explore different wallet providers and compare their features, reputation, and user reviews. Look for wallets that align with appropriate security requirements and have positive feedback from the community.
  3. Download or access the wallet: Once a wallet is chosen, download the app (for hot wallets). 
  4. Set up the wallet: Follow the instructions provided by the wallet provider to set the wallet up. This typically involves creating a password, knowing KYC procedures, and generating a wallet address.
  5. Secure the wallet: Implement the security measures discussed earlier, such as enabling 2FA, backing the wallet up, and keeping software up to date.

Once the Bitcoin wallet is set up and secured, users are ready to securely send, receive, and store Bitcoin.

Creating a Bitcoin Wallet Address

A Bitcoin wallet address is a unique identifier that allows individuals or entities to send Bitcoin to others’ wallets, similar to sending money to a bank account. Below is how users can create a Bitcoin wallet address:

  1. Open the Bitcoin wallet: Launch the Bitcoin wallet software or app and navigate to the ‘Receive’ or ‘Receive Bitcoin’ section.
  2. Generate a new address: Click on the ‘Generate New Address’ or similar option to create a new Bitcoin wallet address. The wallet will automatically generate a unique address.
  3. Copy the address: Once the address is generated, copy it to the clipboard or share it with others using the provided options. Make sure to double-check the address to avoid any mistakes.
  4. Use the address to receive Bitcoin: Share the Bitcoin wallet address with the person or entity who wants to send Bitcoin. They can then use this address to initiate the transaction.

Remember to generate a new address for each transaction to enhance privacy and security.

How to Safely Store Cryptocurrency Wallets

Hardware wallets are physical devices that need to be safely and correctly stored, and both software and hardware wallets require passwords and seed phrases. Below are tips on how to store this information safely.

Hardware wallets

Consider using a hardware wallet for long-term Bitcoin storage. Hardware wallets store a user’s private keys offline, making them less vulnerable to hacking or malware attacks. Keep the hardware wallet in a safe place and ensure it is protected from physical damage.

Backing up wallets

Create regular backups of the wallet and store them securely. This ensures that even if a holder’s device is lost, stolen, or damaged, they can still recover their funds. Encrypt the backup files and keep them in multiple secure locations.

Use a secure computer or device

When accessing the Bitcoin wallet, ensure it is a secure and trusted computer or mobile device. Avoid using public or shared devices that may be compromised.

Keep private keys offline

Never store private keys or wallet recovery phrases on any online platform or in digital format. Write them down on paper and keep them in a secure location, such as a safe deposit box or a fireproof safe.

By following these storage practices, holders can protect their Bitcoin wallet from unauthorised access and potential loss.

For more, here are examples of how scammers might try to extract Bitcoin wallet passwords and seed phrases from users.
