I don`t get why XCH is limited in supply and why it is needed in the first place. Why not use VIA for creating assets?
If the amount of XCH is fixed at the end of september, but it will be very important in the future, isn`t there a "risk" that XCH will get very expensive, which could be counterproductive for its original purpose (it would turn more into a speculative asset itself, wouldn`t it?)?
This question was address previously by Drak. The basic answer was, if the population of XCH is lowered significantly the price of XCH services can be adjusted. For example, it is 1 XCH to create a contract. This could be changed to .1 or .01.
But, I don't think this will be needed for a long time. There's a lot of XCH out there.
