Bitcoin Mining Difficulty Plummets 19.9% Amid Revenue Compression and Shift to AI
Bitcoin's mining difficulty has plummeted by 19.9% from its November 2025 peak of approximately 156 trillion to 126.23 trillion, marking the third deepest decline since dedicated ASIC hardware replaced graphics processors.
This significant drop in difficulty is not just a reflection of a temporary market fluctuation but a symptom of a deeper issue within the mining industry.
The halving of block rewards from 6.25 BTC to 3.125 BTC per block has led to a substantial decline in revenue for miners, with many struggling to break even at current prices.
As a result, publicly traded miners have sold over 32,000 BTC in the first quarter of 2026 alone, exceeding their combined sales for all of 2025 and surpassing the roughly 20,000 BTC sold during the 2022 Terra Luna collapse.
The shift towards AI data centers is gaining momentum, with major mining companies like Hut 8 signing multi-billion dollar agreements to redirect their power capacity towards artificial intelligence initiatives.
