Golden Finance reports that the latest second-quarter production data shows that listed and soon-to-be-listed mining companies are consolidating their share of Bitcoin output. The total market share of these 18 companies has grown from 21.1% in the same period last year to 32.5% in the second quarter. However, this growth is not uniform. The rise in total market share is not widespread but is mainly driven by MARA, Cango, IRE, and CleanSpark, which have significantly increased their computing power, offsetting losses from miners who have shifted to HPC or experienced stagnation in growth.
