Since this operation takes a lot of calculations, a very powerful desktop 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 “classic” 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
