比特币挖矿难度下降 5% 至 79.5 Terahashes，创下 3 月份以来的最低点

7 月 5 日达到 79.50 terahashes（79.5T）的季度低点，比特币挖矿难度下降超过 5%。

Bitcoin mining difficulty decreased by over 5% on July 5, dropping to 79.50 terahashes (79.5T) for the first time since March.

7 月 5 日，比特币挖矿难度下降了 5% 以上，自 3 月份以来首次降至 79.50 terahashes (79.5T)。

The adjustment, which occurred at block height 775,248, brought down the difficulty from the previous measure of 84.09T. This marks a decrease of 5.38% in mining difficulty, with the adjustment being triggered by a slowdown in hashrate.

此次调整发生在区块高度 775,248 处，难度较之前的 84.09T 有所下降。这标志着挖矿难度下降了 5.38%，此次调整是由算力下降引发的。

According to data from BTC.com, the lowest difficulty measure recorded in 2024 was 79.47T on March 11. Difficulty has since risen to an all-time high of 88.10T in April and gradually declined to reach its current level.

BTC.com数据显示，3月11日，2024年难度最低记录为79.47T。此后，4月份难度升至历史新高88.10T，并逐渐下降至目前水平。

Hashrate, a measure of the computational power used in Bitcoin mining, roughly translates to the number of guesses a mining machine is expected to make before solving the cryptographic puzzle and unlocking one of the remaining Bitcoins.

算力是比特币挖矿中使用的计算能力的衡量标准，大致可以翻译为矿机在解决密码难题并解锁剩余比特币之前预计进行的猜测次数。

Hashrates are adjusted every 2,016 blocks, which takes roughly two weeks. Throughout Bitcoin's history, hashrates have largely increased month over month.

算力每 2,016 个区块调整一次，大约需要两周时间。纵观比特币的历史，算力逐月大幅增加。

For instance, in 2014, the hashrate was around 1.1 gigahashes. At this low hashrate, most desktop PCs could mine Bitcoin (although a more powerful and energy efficient rig is needed to be profitable).

例如，2014 年，算力约为 1.1 GB。在如此低的算力下，大多数台式电脑都可以开采比特币（尽管需要更强大、更节能的设备才能盈利）。

Hashrates finally crossed the terahash mark as adoption began to pick up steam towards the end of 2017. They will remain at 79.5T as of July 6, 2024, until the next difficulty change.

随着 2017 年底采用率开始上升，算力终于突破了 terahash 大关。截至 2024 年 7 月 6 日，算力将保持在 79.5T，直到下一次难度变化。

According to mining pool @f2pool_official, an ASIC rig with an efficiency rate of 26 watts per terahash or less will be able to mine profitably at the current difficulty measure of 79.5T, assuming Bitcoin's price remains above $54,000.

根据矿池 @f2pool_official 的说法，假设比特币的价格保持在 54,000 美元以上，效率为 26 瓦/terahash 或更低的 ASIC 钻机将能够在当前 79.5T 的难度下实现盈利。

If the price of Bitcoin drops, more efficient rigs will be needed to keep miners profitable. The largest miners should be able to operate comfortably, especially in regions where mining facilities receive energy subsidies, if all else remains equal.

如果比特币价格下跌，将需要更高效的钻机来保持矿商盈利。如果其他条件保持不变，最大的矿商应该能够舒适地运营，特别是在采矿设施接受能源补贴的地区。
