The hashprice for Bitcoin miners is at a historic low, but the network's hash rate has surged to 429.72M TH/s from 205.77M TH/s a year ago, indicating its strength. Experts differ in opinion: Checkmate highlights the resilience of Bitcoin's proof-of-work mechanism; Beau Breedlove suggests focusing on plain revenue over revenue per hash due to increased hash rate. Checkmate emphasizes considering miner income relative to network value. Nicholas Gregory thinks regulators might opt to prohibit Bitcoin due to the difficulty of challenging proof-of-work. Checkmate stresses that proof-of-work is still expensive for potential attacks.
