• Bitmain has announced that it will no longer ship bitcoin miners to mainland China

  • Bitmain, a Bitcoin mining hardware manufacturer, will no longer ship machines to the Chinese mainland. China addresses the issue.

    The Beijing-based company announced the news on Sunday, stating that it will follow local regulations and suspend domestic delivery beginning Monday, but that international business will continue as usual.

    Bitmain’s move may have little effect on the company because domestic sales have been declining since late last year due to the rise of North American mining operations. The move may formally mark the end of the company’s domestic market share, which accounted for nearly half of its revenues in 2017 and about 40% in the first half of 2018.

    Mining at home

    There has been an increase in the number of at-home mining operations in China using graphics processing units (GPUs), but Chinese authorities have tightened their measures to detect hidden mining operations.

    For example, the Jiangsu provincial government in China recently conducted an investigation into local energy consumption and mining pool IP traffic. It detected over 4,502 suspected mining IP addresses in the province and consumed 260,000 kilowatt-hours of energy. Surprisingly, 21% of those mining IP addresses were discovered to be inside government agencies, public schools, and businesses.

    Based on group chat messages seen by the author, some Chinese miners have recently shared anecdotes of receiving calls from local energy and telecommunications bureaus, who questioned them about mining suspicions and sent staff for on-site inspection due to their abnormal energy consumption.
