The 3600 coins a day inflation does not necessarily have a great deal of effect upon the price in practice. Some of the largest miners do not actually have to sell their coins at all as they have very large VC funding rounds under their belts. Inflation is simply a nice solid reason to blame price weakness. In a similar way when the price rises and the bull market resumes in a few months there will be a reason cited then, too.

The
bitcoin price is unrelated to mining costs or coin inflation (block reward).
