ChainCatcher message, the latest announced production data for the second quarter shows that listed and upcoming mining companies are consolidating their share of Bitcoin output. The total market share of these 18 companies has increased from 21.1% in the same period last year to 32.5% in the second quarter. However, this growth is not uniform. The overall increase in market share is not comprehensive, but is mainly driven by MARA, Cango, IRE, and CleanSpark, which have significantly increased their hash power, offsetting the losses of miners that have shifted to HPC or experienced stagnation in growth.
