The king of mining metrics - the hashprice – shows miners' daily revenue per unit of hashrate production, Terra Hash per second (TH/s). The hashprice is the same for all bitcoin miners, and we can use it to calculate their revenues.
For example, the mining rig Antminer S19j Pro produces 100 TH/s. The current daily hashprice is $0.19 per TH/s. To calculate the daily revenue of this mining rig, we multiply $0.19 with 100 to get $19 per day.
