Desktop wallets have many advantages over online wallets. Although online wallets are easily accessible from anywhere in the world, they are also more vulnerable to potential hacking. On the other hand, desktop wallets can only be accessed through private computers, and personal security keys can only be stored on this computer. Therefore, online exposure of your security key will be reduced. However, if your computer is infected with malware, desktop wallets remain vulnerable to hacking, and malware can erase keys and steal bitcoin.
