比特币 (BTC) 挖矿难度下降 5% 至 79.50 Terahashes，为本季度最低

继 3 月至 5 月网络达到 88.10 太拉哈希的历史最高点之后，出现了下降。

Bitcoin’s mining difficulty experienced a decline on July 5, dropping by over 5% to 79.50 terahashes (79.5T), the lowest in this quarter of the year and the largest since March when the difficulty briefly fell below 80 terahashes (80T).

7 月 5 日，比特币挖矿难度出现下降，跌幅超过 5%，至 79.50 太哈希（79.5T），为今年本季度最低，也是自 3 月份难度短暂跌破 80 太哈希（80T）以来的最大难度。

The fall came after an increase from March to May when the network hit its highest-ever mark of 88.10 terahashes. However, since then it has been decreasing gradually.

3 月至 5 月期间，该网络达到了 88.10 太哈哈希的历史最高水平，之后出现了下降。然而，从那时起，它就逐渐减少了。

Mining difficulty is a measure that reflects the computational power required to mine new bitcoins. It adjusts approximately every two weeks to maintain a consistent block time. Historically, the network’s hashrate has shown consistent growth, with few exceptions.

挖矿难度是反映挖掘新比特币所需计算能力的衡量标准。它大约每两周调整一次，以保持一致的出块时间。从历史上看，网络的算力一直显示出持续增长，几乎没有例外。

For example, back in 2014, hashrate was about 1.1 gigahashes per second meaning that nearly any desktop computer could mine Bitcoin profitably, but later on in late 2017 as adoption increased, it reached the terahash level for the first time.

例如，早在 2014 年，哈希率约为每秒 1.1 gigahash，这意味着几乎任何台式计算机都可以通过挖掘比特币来盈利，但后来在 2017 年底，随着采用率的增加，它首次达到了 terahash 水平。

According to estimates from F2Pool an operator of a bitcoin mining pool, under the current difficulty of 79.5 terahashes, ASIC mining rigs with an efficiency of 26 watts per terahash or better can remain profitable if Bitcoin’s price stays above $54,000 and electricity costs $0.07 per kilowatt-hour.

据比特币矿池运营商 F2Pool 估计，在当前 79.5 Terahash 的难度下，如果比特币价格保持在 54,000 美元以上且电费每千瓦 0.07 美元，则效率为 26 瓦/Terahash 或更高的 ASIC 矿机仍可保持盈利。小时。

Furthermore, the recent difficulty decrease may temporarily improve profitability for some mining operations. However, if Bitcoin’s price declines, only the most efficient rigs will maintain profitability. Larger mining operations, particularly those benefiting from energy subsidies, are better positioned to adapt to potential price fluctuations.

此外，最近难度的降低可能会暂时提高一些挖矿业务的盈利能力。然而，如果比特币价格下跌，只有最高效的钻机才能保持盈利能力。较大的采矿作业，特别是那些受益于能源补贴的采矿作业，能够更好地适应潜在的价格波动。
