Bitcoin Hashrate Surpasses One Zettahash as Miner Revenue Per Petahash Drops to Record Low of $34.20

Bitcoin's network computing power has exceeded one zettahash for the first time, yet miner revenue per petahash has fallen to a record low near $34.20. Mining difficulty decreased approximately 2% to 149.30 trillion at block height 925,344 on November 27, marking the second consecutive monthly decline. Operations using hardware with efficiency below 30 joules per terahash now require power costs under 5 cents per kilowatt-hour to break even, according to Digital Mining Solution.
