esktop wallets are those that are not connected to the Internet; they are also called "cold storage" methods.
The desktop wallet offers a number of advantages over the online wallet. While online wallets are readily available from anywhere in the world, they are also more vulnerable to potential hacking.
On the other hand, desktop wallets are only accessible through your personal computer, and private security keys are stored on this machine. In this way, the exposure of your online security key is drastically reduced. However, desktop wallets are still susceptible to hacks if your machine becomes infected with malware designed to root keys and steal bitcoins.
