MicroBT has expanded its mining hardware production in the U.S. to circumvent tariffs and mitigate supply chain risks. The company now produces over 10,000 units monthly with a 99% yield rate, catering to the growing North American market, which represents over 30% of global mining activity. Riot Platforms has placed a significant order for MicroBT's M66S miner, totaling 18 EH/s. Despite higher production costs in the U.S. compared to China, MicroBT aims to leverage automation and efficiency to balance expenses. However, regulatory scrutiny of Chinese-made hardware in U.S. infrastructure remains a concern.
