Weekly Mining Newsletter
Riot's $9.5M power credits, bitcoin's mining difficulty goes up, and busy earnings weeks ahead.
Highlights of the week
As we mentioned in last week's issue, bitcoin's hashrate has gone up as miners in Texas have resumed operations after curtailment since early July. That resulted in the mining difficulty increase after three downward adjustments in a row.
Because of the curtailment participation, Riot Blockchain said it earned about $9.5 million in power credits that can be used against an energy invoice in the future. That's worth more than half of Riot's direct production costs in Q1, which was ~$19 million.
Next week will be busy with many public miners scheduling Q2 earnings calls and financial report releases. We did an estimation of their self-mining production costs in Q1 based on their income statements. We all know energy rates for bitcoin miners have gone up so it'll be interesting to see how much exactly the cost spike was in Q2.
