It's trivially easy to create an altcoin that inflates to infinity instead. It's just changing a relatively small amount of code. The difference is instead of a political elite that only cares about themselves & their tribe like most human beings, the monetary policy is set at the start and is completely predictable.

Right now bitcoin is the star of the ball, but the other altcoins represent a significant amount of value. There is nothing guaranteeing that bitcoin will stay the star.
