Isn't mining inherently "inflationary" because of things like Moore's law and technological progress? I say inflationary because just like a dollar today is worth less than a dollar in a year because of monetary inflation, a brand spanking new butterfly labs ASIC with 600GH rate is going to be less valuable in a year when that ASIC becomes outdated. Since buying large amounts of these mining devices is a large upfront cost, why would anyone ever choose to go this route?
