According to reports, several U.S.-listed Bitcoin mining companies mainly operating in North America have mined more than 10,500 BTC, of which nearly 40% of the output came from the past two months. They added almost all the mined bitcoins to their company's inventory, which totaled nearly 18,000 BTC as of August, which has more than quadrupled so far this year. According to data, Riot, Marathon, Bitfarm, Hut8, and Argo mined a total of 1,796 BTC in August. This is slightly lower than their collective production in July, but so far, their production in the third quarter has reached or exceeded the production record in the second quarter. Their collective output accounted for nearly 5% of the total Bitcoin mining revenue so far this year.
