24. Cryptocurrency wallets: Hot Wallet vs. Cold Wallet – key differences!

Cryptocurrencies such as Bitcoin and Ethereum are attracting increasing attention from investors and users worldwide. However, one of the most critical aspects of investing in these digital assets is their proper storage. In this context, two main types of cryptocurrency wallets are emerging: hot and cold.

Cryptocurrency wallets are essential for securely storing our private keys. To choose the right one, you need to understand the basic difference between Hot Wallets and Cold Wallets.

In today’s lesson, we will discuss these concepts and the key differences between them. The important point, however, is that both types of wallets protect our private and public keys. Deciding the right wallet can be challenging and depends on many factors, including the number of cryptocurrencies you hold, your preferences, security, or ease of access to your funds.

Hot Wallet – Fast but Risky! 

A Hot Wallet, also known as an internet wallet, is a type of cryptocurrency wallet that is permanently connected to the internet. It is a solution that provides quick access to digital assets and enables easy transactions. Hot Wallets are popular among people who use cryptocurrencies on a daily basis.

Hot Wallets are accessible from devices such as mobiles, tablets, laptops, or computers – essentially, any hardware with internet access. They have become widely accepted in the cryptocurrency ecosystem due to their ease of use.

How does such a wallet work? Very simply, it stores the private keys of cryptocurrencies after they have been purchased or mined.

Let’s now look at the advantages and disadvantages of this type of portfolio:


  • Quick access to cryptocurrencies.
  • Convenient for everyday use and transactions.
  • Ability to access from different devices via a browser or app.


  • High risk of hacking attacks, as these wallets are always connected to the network.
  • Risk of loss of funds in the event of an attack or burglary.

Types of hot wallets

Hot Wallets come in different types and serve various purposes. They can be mobile apps, web wallets, or ecosystem-specific wallets. The choice of Hot Wallet depends on the user’s needs.

Examples of such wallets include MetaMask, Trust Wallet, Coinbase Wallet, Exodus Wallet, Edge, or Robinhood.

Cold Wallet: safer but less convenient! 

A cold Wallet is the counterpart to a hot wallet. It is a solution that stores cryptocurrencies offline, away from the internet. There are different forms of Cold Wallets, but the two most popular are paper wallets and hardware wallets.

Paper wallet: This is a physical document or card that stores the private and public keys of the cryptocurrency wallet. Paper wallets operate entirely offline and are impervious to network attacks. However, they require secure physical storage, ideally in a safe.

Hardware wallet: This is a specialized device designed to store cryptocurrencies offline. It is more convenient than a paper wallet, as it allows secure transactions via a USB or Bluetooth connection.

Deep cold storage: This is a type of wallet that takes additional security measures, such as storing a cold wallet in a bank vault or safe deposit box. It is designed for people who need minimal access to their assets.

Advantages of Cold Wallet:

  • The highest level of security because it is offline.
  • Minimal risk of losing funds due to hacking attacks.

Disadvantages of Cold Wallet:

  • Slower access to cryptocurrencies, as it requires a network connection to carry out transactions.

Interesting fact: After the FTX exchange collapse in November 2022, cold wallets gained even more adoption and popularity. The exchange reported a hack resulting in the theft of users’ digital assets as the reason for the collapse.

Which Wallet Is Better? 

There is no one-size-fits-all answer to this question. It depends on your needs and preferences. Your choice of wallet should align with your specific requirements.

Hot wallets are suitable for traders who actively trade cryptocurrencies daily, while cold wallets are great for long-term holders (HODL’ers).

Which portfolio is safer?

 Cold wallets are considered safer because they are offline and not exposed to the internet. With this type of wallet, you as the user have complete control over your private and public keys.

Summary: The choice between a Hot Wallet and a Cold Wallet depends on the individual needs and priorities of the investor. Many cryptocurrency investors opt for a combination of both types of wallets: hot wallets for everyday use and convenience, and cold wallets for securely storing larger amounts of cryptocurrencies. It is essential to understand the differences between the two and decide which type of wallet best suits your own needs and level of familiarity with cryptocurrencies. It is also wise to secure hot wallets with strong passwords and two-factor authentication to minimize the risk of losing funds.
