This is a service owned by a third party. Depending on the wallet device, the keys are stored on a remote server or downloaded as an encrypted file to the user’s computer. They allow not only to open several wallets for different cryptocurrencies but also to carry out convertible operations, trade on exchanges, calculate commissions with the help of built-in calculators, etc.


  • Quick registration;
  • Anonymity. Verification is not necessary;
  • Ability to work with multiple cryptocurrencies.


  • Risks inherent in cryptocurrency exchanges. There is a possibility of a wallet to be hacked;

3. Hardware wallet

This is a separate removable device like a flash drive. This method of storing keys is not very popular yet, because it is suitable only for long-term storage (it is inconvenient to trade with it). But it does not overload the computer.


  • Private keys are never exposed to your computer. The hardware is immune to computer viruses.
  • Your hardware requires you to confirm a transaction on your device (not the app on your computer) before any coins can be spent.


  • The only downside to hardware wallets is that they cost money. However, it might be worthwhile to consider investing in a hardware wallet because they are more secure, especially if you hold a significant amount of coins.

Examples of popular hardware wallets:

KeepKay. Supports 4 major cryptocurrencies.

4. Desktop wallet

These are the programs that you install on your computer.


  • Desktop wallets store keys on your hard drive, which is considered as one of the most reliable options among the offline wallets. It is a program installed on your computer with which you can access data about your cryptocurrency account.


  • Their disadvantage is the need for constant updating, which takes plenty of memory. That’s why desktop programs are divided into “thick” and “thin”. “Thick” (“heavy”) wallets are those that download the whole blockchain on your computer and keep it updated. “Thin” (“light”) wallets  download the necessary information from third-party services. Despite the fact that the file with the key remains on the computer, there is a risk that the data from the services will not be downloaded the ones that are needed.

Examples of popular mobile wallets:

Exodus. Has an integrated exchange platform ShareShift supports 7 cryptocurrencies.
Bitcoin Core. One of the best wallets for bitcoin, working with all operating systems.
Armory. In addition to Bitcoin Core, which allows you to increase the level of storage security.

5. Paper wallet

Each wallet has its advantages and disadvantages. Which option to choose depends on the goals.
