Hot and cold wallets
By determining whether a wallet is connected to the Internet or not, we can distinguish the category of that wallet. The reason why we should recognize those two categories is that there are pros and cons for each type of wallets.
“Hot” wallets are those which connected to the Internet. We can use our devices to access our funds anytime that we want. However, by connecting to the Internet, it is quite obvious that “hot” wallets are invulnerable, but it depends on which type of “hot” wallets to identify how secure it is. Typically, for “hot” wallets, we have online desktop wallets, mobile wallets, web wallets.
“Cold” wallets are not connected to the Internet. We can store our funds offline, so basically this method is considerable more secure than “hot” wallet. However, there are risks that remain. For “cold” wallets, we can include offline desktop wallets, hardware wallets, and paper wallets.
Desktop wallets
Desktop wallets are the most commonly used type of wallet. They are software programs that can be installed to our computers. Therefore, we can connect to a coin’s client platform through those software programs, via the internet. Some offline desktop wallets (“cold” wallets) do not connect to the internet in order to serve storing crypto purposes.
Offline desktop wallets are built to operate with lesser risks and are perfect for storing a large amount of cryptocurrencies. They work with numerous platforms including Windows, Mac and Linux, and some are also compatible with hardware wallets.
Pros:

Paper wallets are physical documents that carry all the necessary data needed to generate private keys of a given cryptocurrency. The paper contains copies of the public and private keys that make up a wallet, and QR codes that can be scanned when adding keys into software during the making of a transaction. For this type of wallet, we create some randomness by typing characters into the generation form as we generate the wallet, generate the form and then print a hard copy.
