Crypto mining means the operation of calculating the transaction block hash. That is a integral part of anything based on the blockchain technology. Since this action takes a lot of calculations, a high-end computer is required. Exactly, the GPU is better for this purpose, because they have more cores available. Cryptomining farms usually consist of tens and hundreds of graphic cards to complete their task efficiently. Such computer systems are not usable for “classic” purposes, like gaming or browsing the Web. Crooks who make profit via this coin miner use someones’ hardware instead, even if they are used for the regular activity.¹
