It is crystal clear that since the introduction of bitcoins, more and more have been issued through mining. The mining process is the control measure of the supply of the bitcoins to the market. However, with time the bitcoins keep increasing, meaning that inflation is at work. As years progress, we are going to see the value of the bitcoin reach its maximum and now start reducing. Considering the pace in which all these is happening, this might take a few more years.
Bitcoin is mostly immune to all types of inflation, but some kinds like fractional-reserve banking can still happen.The price of bitcoins will change over time, and nobody has a crystal ball that can predict the price.
