The Bitcoin mining firm Riot Blockchain produced 318 BTC in July, valued at around $6.88 million, from its mining operations located in central Texas. The firm also received $9.5 million in power credits for switching off their power-hungry Bitcoin miners during all-time-high energy demands in a month where the state has been experience extreme heat waves.

A press release from Riot proudly announced that "Riot curtailed a total of 11,717 megawatt hours in July, enough to power 13,121 average homes for one month", as though it is acceptable that they are normally using this amount of electricity solely to churn out Bitcoins.

They also wrote that "When applied to anticipated power costs for the month, the power credits and other benefits are expected to effectively eliminate Riot’s power costs for July"—meaning that Texas residents are effectively subsidizing the cost of Bitcoin mining whether they like it or not. Meanwhile, the Texas Tribune and The Dallas Morning News report that many Texans are paying 50–70% more for electricity than this time last year.
