The price of Bitcoin? What do you mean? A Bitcoin is a Bitcoin. What it will buy will always increase over time.

That isn't a given. Likely, yes, but not given. It depends on people wanting it. Lack for people or lack for want will decrease it's worth. Both are possible.

Yes but it's the best money mankind has ever made. People will want money that can't be debased when theirs is debased. Bitcoin cannot be stopped as a network. Until a better money comes along, this is the evolution of money as we know it. Bitcoin is the only option on the horizon in perpetuity.
