**[Data: Bitcoin Miners' Profit Margins Continue to Face Pressure, Revenue Falls Below Production Costs]** Odaily Planet Daily News: Bitcoin miners' revenue has been declining over the past year, with the current 7-day moving average daily revenue at approximately $30 million, significantly lower than last summer's level of over $50 million. Among this, transaction fees contribute less than $250,000 per day, which is almost negligible compared to block subsidies. Meanwhile, Bitcoin's price is hovering around $62,500, below JPMorgan's estimated production cost of approximately $78,000. This state of prices being below production costs has persisted for five months, marking the longest duration in this cycle. Historically, production costs are often considered a soft bottom range for Bitcoin prices. Currently, it is estimated that about 20% of miners are operating at a loss under the current price levels, and this pressure is beginning to reflect at the network level. Over the past six months, the sensitivity of mining difficulty to Bitcoin prices has risen to 0.62, indicating that high-cost miners are increasingly inclined to turn mining machines on and off based on price fluctuations rather than continuing to mine at a loss. In the second week of June, Bitcoin mining difficulty decreased by 10%, marking the second significant adjustment of this magnitude this year. A similar adjustment occurred in the first quarter, with both instances happening during periods when prices remained below production costs, highlighting the growing pressure on miners. (The Block)
