According to data from Hashrate Index, despite Bitcoin's increase of over 113% this year, most mining stocks have performed poorly, with a clear downward trend in 2024. Among the 25 listed mining companies, only 7 achieved positive returns this year, including Core Scientific (CORZQ) up 327%, TeraWulf (WULF) up 169%, Bitdeer (BTDR) up 167%, Hut 8 (HUT) up 91%, Iris Energy (IREN) up 72%, Northern Data (NB2) up 58%, and Cipher (CIFR) up 33%. In contrast, Argo Blockchain (ARB) saw a decline of up to 84%, and Hive (HIVE) fell by 29%. Although mining companies are actively diversifying their businesses through financing and entering AI sectors to offset the earnings pressure after the halving, they still face challenges such as increasing mining difficulty and soaring operational costs, with some companies reporting a mining cost of over 50 thousand dollars per BTC.
