Bitcoin miners' total revenue reached $1.086 billion in May, marking the highest level in four months and surpassing the $1 billion mark for the first time since January. Block subsidies accounted for $1.079 billion of this total, with transaction fees contributing minimally. Despite this revenue increase, miners face profitability challenges due to declining Bitcoin prices. Hashrate has decreased from over 1000 EH/s to below 975 EH/s, and daily income per PH/s has dropped 17.82% from $37.44 to approximately $30.77. The block production interval has extended to 10 minutes and 49 seconds, with a potential 7.5% network difficulty reduction expected around June 13. Transaction fees as a percentage of block rewards have risen from under 0.6% to about 1.16% in the past 24 hours, offering miners slight relief.
