BTC's rise to record highs earlier this week is expected to allow miners to extend their November profitability into December, according to a report by investment bank Jefferies on Wednesday.
Bitcoin mining economics improved in November as the average price of bitcoin was 31% higher while the average network hashrate rose by almost 4%, the report said.
The hashrate, representing the total computing power dedicated to a network, is a proxy for competition in the industry and mining difficulty.
