Similarly, revenue of $24.92M at the end of June missed the consensus of $29.7M and decreased from $29.3M at June 30, 2021, reflecting lower revenue per bitcoin mined, partially offset by an 8% increase in bitcoin production activity.Impairment of digital currencies mounted to -$127.6M at June 30 vs. -$11.1M at June 30, 2021.Q2 operating loss of $178.2M deepened from -$110.3M in Q2 of last year.
