In January 2025, major Bitcoin miners, including Hut 8, Mara, and Bitfarms, experienced reduced production due to a significant rise in network difficulty. This difficulty level has increased by 27.8% since the last halving in April 2024, now standing at around 110 trillion.
Contrarily, Riot Platforms managed to increase its Bitcoin production by 2.1% due to the launch of a new mining facility in Texas. This contrasts with declining outputs from other miners, showcasing the varying impact of rising difficulty across the market.
