Despite rising mining difficulty, the top 11 Bitcoin mining companies by market capitalization recorded impressive production gains in October.
According to data from Farside Investors, these companies collectively increased their output by 13%, reaching a total of 3,630 BTC mined—marking their highest production levels since the April halving event.
Marathon Digital Holdings (MARA) led the way with a remarkable 717 BTC mined in October, followed by CleanSpark (CLSK) with 655 BTC, and Riot Platforms (RIOT) with 505 BTC.
Terawulf (WULF) was the only major miner to see a slight production decline, producing 150 BTC, down from 176 BTC in the previous month.
This growth comes amid two difficulty adjustments in October, which increased mining difficulty by an average of over 3% each time, as reported by the Hashrate Index.
The challenges have continued into November, with an additional 6% difficulty hike so far. The next adjustment on November 18 is projected to further raise mining difficulty by over 2%.
For Bitcoin miners, rising difficulty is often a signal of higher competition within the network, as more miners add computational power to secure the blockchain.
Despite these pressures, the leading miners continue to find ways to maximize their output.
