Five publicly-listed North American Bitcoin mining companies produced 1,802 Bitcoins in July-an, an average of 58% more than in June. According to the July production update released by each miner before Tuesday, Marathon Digital, Riot Blockchain, Argo Blockchain, Bitfarm, and Hut8, all showed significant productivity in July, although their computing power did not increase significantly. This is mainly because the Bitcoin network witnessed the most significant decline in Bitcoin mining difficulty in history last month after China issued a shutdown order to the local Bitcoin mining business in June. As a result, the market share of non-Chinese Bitcoin mining pools and mining operations outside China has increased significantly.
