Bitcoin’s mining difficulty dipped slightly to 126.4 trillion after hitting a record high of 126.9 trillion. Higher difficulty and hashrate increase miner competition and costs. Some mining companies, like MARA, expanded operations despite challenges. MARA mined 950 Bitcoin in May and holds 49,179 BTC in reserves, following a Bitcoin treasury strategy.

CleanSpark, a clean energy-focused Bitcoin miner, saw a 9% increase in BTC production, mining 694 BTC in May. The company’s total BTC reserves now stand at 12,502. CleanSpark raised its hashrate to 45.6 EH/s, a 7.5% increase from the previous month. Mining firms are shifting to a Bitcoin treasury strategy, retaining mined coins as assets.
