The percentage of days in which mining at the current hash rate and difficulty would have been profitable. Indicates the overall health and sustainability of mining.
Sustained periods of unprofitable mining historically precede miner capitulation and often occur near bear market bottoms.
The percentage of total miner revenue derived from transaction fees vs. block subsidies. As block rewards halve, fee revenue becomes increasingly important for mining sustainability.
The daily revenue miners earn per unit of hash rate (typically per terahash per second per day in USD). The key economic metric for mining profitability.
Compares the 30-day and 60-day moving averages of Bitcoin's hash rate. When the 30d MA crosses below the 60d MA, it signals miner capitulation; crossing back above signals recovery.
The total computational power dedicated to Bitcoin mining, measured in exahashes per second (EH/s). Higher hash rate = more secure network.
