Mining metrics are calculated based on a network hash rate of 35,367,482,836 GH/s and using a BTC - USD exchange rate of 1 BTC = $ 7,697.74. These figures vary based on the total network hash rate and on the BTC to USD conversion rate. Block reward is fixed at 12.5 BTC . Future block reward and hash rate changes are not taken into account. The average block time used in the calculation is 600 seconds. The electricity price used in generating these metrics is $ 0.12 per kWh. Network hash rate varies over time, this is just an estimation based on current values.
