Just kidding: Miners really have it tough. Last week, as the price of Bitcoin rose, the overall network hash rate also reached a new high, and the competition among miners can be said to be very intense.
However, with this week's price correction, the hash rate has also seen a noticeable decline. I guess this may be because some low-hash-rate mining machines only operate when the price of Bitcoin is relatively high. When the price fell below 70,000, many inefficient mining machines stopped working, leading to a significant drop in hash rate.
