Other companies have gotten shockingly rich off ASICs. The most famous is Bitmain, a Chinese that started off selling their Antminer line of ASIC-powered mining rigs. Bitmain now controls 70-80% of the Bitcoin mining hardware market.[363] Bitmain became so flush with cash that it has since branched out into running a cloud mining firm[364] and mining pools. Its two largest mining pools, AntPool and BTC.com, once owned almost half of the world’s mining power.[365]
