Miners are returning to Bitcoin as difficulty drops and revenues reach all-time highs.
Bitcoin (BTC) miners collected $60 million on a thirty-day average timeframe as of May 5, showing the first signs of recovery after last month's severe revenue drop that followed mass miner outages in China's energy-rich provinces.
In April, coal mining accidents and subsequent inspections in Xinjiang lacerated energy supply to the regional cryptocurrency mining industry. That forced miners to turn off their Application Specific Integrated Circuit (ASIC) hardware, which exclusively generates computing power to secure and put the "work" into Bitcoin's proof-of-work.
