The year 2021 was a landmark for Bitcoin, with its price reaching all‑time highs and sparking a new wave of interest in mining. Miners around the world faced a mix of opportunities and challenges: chip shortages constrained the supply of new ASIC and GPU hardware, mining difficulty climbed to record levels, and regulatory changes—most notably China’s crackdown on crypto mining—forced a geographic shift of hash rate to North America, Kazakhstan, and other regions. Despite these headwinds, both hobbyists and industrial operations expanded capacity, seeking cheap electricity and efficient equipment.
