Bitcoin miners lost $1.5B in mining capacity in H1 2026 amid shift to high-performance computing.

In the first half of 2026, publicly traded Bitcoin miners lost about 75 exahashes per second of mining capacity, valued at roughly $1.5 billion in equipment. This decline reflects a shift as some miners, like Cipher Digital, transition mining rigs to high-performance computing, resulting in significant impairment charges. Core Scientific also reported $266.5 million in equipment write-downs due to lower Bitcoin prices and reduced mining revenue. These changes highlight the industry's reassessment of mining assets and the uncertain financial outcomes of converting to new technologies.

While Bitcoin miners face a $1.5 billion loss in rig value due to a 75 exahash decline, Core Scientific's stock on Pluang trades at Rp394, slightly up by 0.38% as of Oct 04, 2026 16:01 WIB. Despite the impairment charges reported, Core's market cap stands at Rp593.99 million with a balanced buy-sell order activity, showing steady investor interest amid the sector's challenges.
