Bitcoin is not immune to inflation either, but that might over complicate the story somewhat. As long as the fiat inflation rate stays low and Bitcoin continues to appreciate at a rapid pace that it has done until recently, the effect of fiat inflation may be negligible for most investors. The only way to escape it completely would be to stop denominating Bitcoin in fiat. Then, perhaps, 10 years from now, we would be discussing how many Satoshis one might hope to buy with a dollar.
