币界网报道：Bitcoin’s [BTC] global hash rate has dropped sharply by nearly 30% over the past three days, coinciding with the U.S. attack on Iran’s nuclear facilities. Since the June 21 attack, the hash rate has dropped from 954.6 EH/s to 693.5 EH/s, a 27.3% drop as of press time. In other words, computing power has dropped, or miners participating in the Bitcoin network have unplugged their machines. This portends short-term pessimism. This could stem from factors beyond the recent tensions between Israel, Iran, and the United States. BTC Mining Speculations in Iran Some have speculated that the sharp drop in hash rate following the attack suggests Iran may have been using nuclear power to mine BTC. This view is echoed by Max Keiser, a Bitcoin policy advisor in El Salvador. He highlighted BTC’s ability to be a “hedge” amid geopolitical tensions. Keiser added. For Simple Mining, a BTC mining equipment repair company, the drop in hash rate is “good for miners’ profitability.” The company noted that Bitcoin's mining prospects depend on the upcoming network difficulty adjustment, which will determine how hard it will be to find the next block. If the difficulty drops, computing and energy costs will fall, potentially attracting more miners and increasing the network's hash rate. However, miners' daily revenue has taken a hit, falling to $34 million from nearly $50 million over the weekend, according to Ycharts. Meanwhile, data from MacroMicro shows that it costs $98,600 to produce one BTC as of June 21. With Bitcoin trading at around $101,000, miners are currently operating on low profit margins. Others have linked the recent drop in hash rate to miners in Texas unplugging their machines due to rising electricity costs caused by the summer heat wave. That is, higher BTC mining costs could erode miners' profitability and prompt them to sell their reserves. It is therefore worth keeping an eye on this aspect in the short term to see if there are any structural adjustments.
