According to the latest research by cryptocurrency mining company HASHR8, the market for bitcoin mining machines is heating up. John Lee Quigley, head of bitcoin media and product research at the company, said that whenever the price of bitcoin rises sharply, the mining machine market will be affected because miners must further expand their mining business to earn higher profits, and new miners must also ensure favorable mining conditions. John Lee Quigley analyzed that since Bitmain and MicroBT previously claimed that mining machine orders had been scheduled until May 2021, miners had to turn to the secondary market, and the price of new mining machines has risen by 35% since November 2020. John Lee Quigley also disclosed a piece of news that he estimated that Marathon Patent Group is currently the mining company with the most orders for the latest mining machines. If all goes well, the company will receive 6,000 Bitmain S-19J Antminers in August 2021, and then get another 4,000 of the same mining machines in September 2021.
