As the years went by, bitcoin hash rate increased in leap and bounds. 2013 had the hashrate equaling ten Antminer S9 devices. By 2015 the hashrate was 400,000 Th/s corresponding with 30,000 S9 devices. From2017 to August 2018 bitcoin hashrate was at its peak reaching approximately 14,000,000 Th/s and 1,000, 000 S9 devices. During this duration, everyone with an idea about mining jumped right in. Mining was on an industrial scale. However, after this point, the stagnation began. Winter took over the market and it was a long period of setback. The number of miners stopped increasing and the present bitcoin price is not enough to acquire any new equipment.
