Bitcoin’s hashprice has fallen to its lowest level in five years, according to Luxor, now sitting at $38.2 PH/s. Hashprice, a term introduced by Luxor, measures the expected daily value of one terahash per second of computing power. The metric reflects how much revenue a miner can expect from a specific amount of hashrate. It can be denominated in any currency or asset, although it is typically shown in USD or $BTC.
Hashprice depends on four key variables: network difficulty, the price of bitcoin, the block subsidy, and transaction fees. Hashprice rises with bitcoin’s price and fee volume, and falls as mining difficulty increases.
