BTC prices declined a lot during the last period, while difficulty dropped also, but less. Electricity bills are paid in USD so IRM was spending more mined BTC for electricity. IRM also published a transparent report in news channel, you can see all results from September, October and November.
You can find news channel here: https://t.me/ice_rock_news. News channel is very useful for important updates because IRM will first share in news channel. 

And Mr. Dias! You can be proud to build such an impressive project in this bad market. Thx for your effort and all work of IRM team!
