Who is not speculating? Even the 1% buying public has some rough speculations running inside their heads, about what will happen to the USD's value in the next years, about how much purchasing capacity would be left with their monthly allocation for groceries in the next couple of years, about whether the upcoming elections' results would somehow affect it, and so on. Bitcoin adversaries will have to think of new arguments. This kind of loose argument will not sway the public's view on Bitcoin.
