BitFuFu mined 137 BTC in October, down from 167 BTC in September, while its managed hashrate remained broadly stable at 19.5 exahashes per second (EH/s), compared with 19.4 EH/s a month earlier. The company attributed part of the decline to an 11.8% increase in Bitcoin network difficulty, which rose from 132.76 trillion to 148.36 trillion during the month. Self-mining output dropped to 67 BTC from 98 BTC, while cloud-mining production was nearly unchanged at 70 BTC versus 69 BTC. BitFuFu’s Bitcoin holdings increased to 1,454 BTC from 1,388 BTC, showing that production and treasury growth are separate measures. Average fleet efficiency improved to 16.3 joules per terahash from 16.7, while power capacity under management fell to 317 megawatts from 324 MW. The figures illustrate why managed hashrate alone does not determine mining output or profitability. The next update should help show whether October’s weaker production persisted under the subsequent difficulty environment. BitFuFu’s figures are unaudited operating metrics rather than a complete measure of profitability.
