There is some big stone proof-of-work in Paris: How long does it usually take to mine a bitcoin block? The cryptocurrency economy is negligible. The index is built on the premise that miner income and costs are related. Even though the total network hashrate can easily be calculated, it is impossible to tell what this means in terms of energy consumption as there is no central register with all active machines and their exact power consumption. All I see is them trying to convince each other. The pressure is social as well as financial — banks care quite a lot about reducing environmental impact. I will produce more than I consume, and with the excess, I will mine bitcoin. The lower the energy costs as a share of total cost, the more true this is. Load More.
