Its wrong to say:
(Token amount keeps decreasing)
when a new instance of a Drps or 2 new instances of Drpu is/are put into circulation for each burnt Drp token.
It is important to put things right to avoid any kind of possible misinterpretations.
If you start out with 10 red houses and paint 3 of them yellow, you then have 7 red houses which is less than 10 red houses, but you still have 10 houses.
It's correct. When you pay a small fee to switch between DRPS<>DRPU, the fee will automatically get burnt, thus decreasing the total token supply each time the token changer is being used.
Decreasing coin supply is good. I dont know however how often people will change and why they would change. They might want to change just before dividend distribution but then the target coin will be trading at price plus dividend. Will the coin changer take into account that it is just before dividend time and adjust the ratio or will the ratio remain the same always?
