It is not as important as processor for system work, so Jin.exe coin miner viruses don’t waste time on trifles and utilize all of it. It often may cause bad effects.

Crypto mining term means the operation of calculating the transaction block hash. That is a basic part of anything based on the blockchain technology. Since this action takes a lot of calculations, a strong PC is needed. Exactly, the video card is better for this purpose, because they have more cores available. Cryptomining farms are usually constructed of dozens of video cards to conduct their activity effectively. Such computer systems are not usable for “general” purposes, like gaming or web browsing. Crooks who gain money via this coin miner use someones’ hardware instead, even if they are used for the regular activity.²

Compact and well-protected CPU cooling system is not very easy to damage. Meanwhile, GPUs have big and easy-to-access rotors, which can be easily cracked if affected while spinning, for instance, by the user much earlier before the virus injection.
