The cryptocurrency mining industry experienced a surge in activity during May 2025, with major players like CleanSpark and Marathon Digital Holdings (Mara) setting new records. CleanSpark’s production of 694 BTC marked a significant increase from April, while Mara achieved its highest monthly Bitcoin output yet at 950 BTC. Despite challenges such as rising network difficulty and increased competition, these companies leveraged their strategic advantages to achieve impressive results. CleanSpark boosted its hashrate and treasury, exceeding previous performance benchmarks, highlighting the company’s infrastructure-driven approach. Meanwhile, Mara’s self-operated mining pool and technological prowess played a key role in achieving record block production rates. However, the industry faces legal hurdles with Malikie Innovations suing Marathon and Core Scientific for patent infringement related to Elliptic Curve Cryptography (ECC), which underpins Bitcoin technology. This lawsuit could significantly impact the future landscape of Bitcoin mining.
