2) Seems to assume that one cannot control prices by controlling supply. I believe that is false. While the fed has indeed printed a lot of money, they could drive the value of the dollar to zero if they wanted to print billions of dollars and give them to every person on the planet.
Increasing supply to decrease price is the easy part. Decreasing supply to increase price is the impossible part.
If the coin has any merit and the user numbers are therefore growing, you don't need to decrease the supply, you only need to limit it.
