The global digital asset mining sector is witnessing a significant shift as Bitcoin mining loses its dominance to AI-driven high-performance computing. As of December 19, 2025, Bitcoin's price has dropped to $86,000 from a previous high of $125,000, while the hash rate remains above 1,000 EH/s. This has resulted in tighter margins and increased costs for mining firms. Companies like IREN and Core Scientific are pivoting towards AI, with IREN securing a $9.7 billion cloud computing deal with Microsoft. This move highlights a growing divide between firms focused on Bitcoin and those investing in AI infrastructure, as financial data underscores the sector's evolving landscape.
