the computing power of Bitcoin has reached an unprecedented level, with the 7-day moving average computing power exceeding 1 ZH/s (zetta hash per second) for the first time over the weekend. This milestone highlights the continued growth and resilience of the Bitcoin network, but at the same time, miners' profitability is being squeezed due to the rising mining difficulty and declining transaction fee income. According to network data, the sharp increase in computing power is expected to trigger a difficulty adjustment of over 7% in the next two days, further raising the computing threshold required to mine new blocks. Throughout the summer, as the peak electricity restriction period ends, computing power is gradually returning to the network, and mining difficulty is at a historical high. The increase in network computing power comes at a time when transaction fee income is at one of its weakest levels in recent years. In August, transaction fees accounted for less than 0.8% of the total block rewards, hitting a multi-year low.
