Mono and multi-currency wallets

According to the number of supported coins, wallets are divided into mono-wallets and multi-currency wallets.

Mono wallets, as it is already clear from the name, store only one type of currency. As a rule, it is quite powerful, well-protected software. When working with such a wallet, a large amount of data is downloaded to your computer or phone. These wallets require a lot of disk space, they constantly need to be synchronized.

Agree, this is not very convenient for constant work. However, this is one of the most reliable ways to store crypto. Especially if you have a separate laptop with different degrees of protection under your monocurrency wallet, for which no one but you will no longer work.

Multi-currency wallets support several popular currencies. What is a multi-currency wallet? Basically, it is an interface for managing your funds.

Usually these are the most popular and popular coins from the top 10 or top 15. Wallet developers are constantly adding new coins to them. Some wallets, such as Jaxx, already have a built-in Shape Shift exchanger. And so right in it you can convert major currencies: Bitcoin, Bitcoin cash, Ethereum, Ethereum classic, Litecoin.

Jaxx can be installed on your smartphone, and you can also log in via the web interface. However, there are reports that the web version has insecure keys. We recommend using the mobile version of this wallet.

Not bad wallets are Coinomi, Exodus. They have almost all the same features as Jaxx.
