The bitcoin mining industry has witnessed massive change over the past two years. Cold War arms race, additional investments may prove unsustainable in the long run due to ROI constraints. Currently, miners are hitting the wall. Technology is the first problem. 16nm FinFET ASICs are expected next year. Yet progress is slowing down due to a number technical limitations plaguing all chipmakers. The second problem involves economics.

It is more down to earth, but it is closely related to chip design and manufacturing. Bigger chips manufactured on relatively immature processes tend to be costlier to produce and develop. They usually face yield and leakage issues as well. The first technical challenge can be described as the thermal barrier. Simply adding more transistors and building massive chips with billions of transistors delivers more performance, but cooling these chips becomes troublesome and impractical. At the same time efficiency becomes an even bigger problem. As an emerging field of IC design, bitcoin mining ASICs have experienced rapid evolution over the past two years.
