Cold and hot cryptocurrency wallets: overview, examples, advantages and disadvantages


Cryptocurrency wallet is a program or device for storing private and public keys of a cryptocurrency user. It guarantees that no one else will get access to funds, but at the same time requires careful attention, because if you lose your data, then the owner will not be able to use his capital.

A crypto wallet should be convenient and secure. Today, the editors talk about hot and cold wallets – what this means, how they differ from each other and how to make the right choice.

Difference between cold and hot cryptocurrency wallet

Hot wallet is an internet-connected cryptocurrency wallet. As a rule, it is easier to start, configure and use. However, these wallets are more susceptible to technical vulnerabilities, hacker attacks and regulation.

Cold storage – storage that works without an Internet connection. It is several times safer, but it has a limited choice of supported currencies, and in addition, requires the purchase of an expensive device.

An investor may have different reasons for using a particular type of storage. Most often, both options are used at once.

Features and Benefits of Hot Wallet

A hot wallet is ideal for fast and frequent transactions, while a cold wallet is ideal for storing long-term investments that are not planned to be touched. At the same time, only a small percentage of the total capital is kept in the hot wallet – “for small expenses”. If they are lost, there will be no big trouble.

Some investors prefer to keep cryptocurrencies and tokens on accounts of popular crypto exchanges such as Binance or Exmo. These companies act as hot wallet service providers. They store funds inside their infrastructure, and if an attacker gains access to the server, they can get to client accounts.

When choosing a hot wallet, pay attention to the following factors:

✅  What cryptocurrencies does it support – only bitcoin, or also altcoins, rare tokens.

✅  Security – two-factor authentication is supported, the site address starts with HTTPS, and payments are made using the HD system (hierarchically determined) – a new address is used each time to receive a payment.

✅  Multisignature function if you want to share the software with other owners.

✅  A simple and logical interface that allows you to quickly start making transactions.

✅  Reputation in the crypto community, transparency of the development team, open source.

In general, the hot storage option is suitable for those who value ease and quickness of learning, do not worry too much about privacy and do not plan to store large amounts of cryptocurrency.

Pros and cons of a hot wallet

Pros: ✅

✅  Most of them are free.

✅  Instant access to cryptocurrency – just launch the application.

✅  Maximum simplicity and user friendliness.

✅  A wide range of additional functions.

✅  Support for a large number of coins and tokens.

Cons: ❌

❌  Security is questionable, as hot wallets, by definition, are always connected to the internet when launched.

Features and benefits of a cold wallet

Any crypto assets that you don’t need instant access to are best stored in a cold wallet offline. Security is a key factor in the entire crypto industry. There are options like a hardware wallet or a paper wallet.

A hardware wallet is an external device, similar to a USB flash drive, that stores private keys. Hackers cannot remotely access it, because the owner must confirm it to complete any transaction. If the device is lost, there is still no danger, since the access is protected by a PIN code.

A paper wallet is a printout of the private key and public address on a piece of paper. The method is safe enough if you are sure that no one will find the paper and it will not burn or get wet.

Cold storage selection factors:

✅  Safety is top priority. You should focus on trusted service providers who have a good reputation.

✅  Ease of use. It’s a little more difficult anyway than using a hot wallet, but still not desirable for learning to take too long or inconvenient to use.

✅  Access. You need to decide what is more important to you – 100% safety or convenience. Because the easier it is for you to access your funds, the theoretically easier it is for an attacker to do this.

And finally, since we are talking about a physical device, then size, weight and appearance will play a certain role in the choice. It all depends on personal preference.
