50% of the supply of NOVUS will be available for VIDZ swap.
The amount of VIDZ to be swapped is up to whoever want to do it. If only one person with 100k sign up for the Swap he will have 50% of the Novus as an example.
So if 100% of all VIDZ is swapped and burned (1 VIDZ = 0.5 NOVUS).
But if only 10% of VIDZ is swapped and burned (1 VIZ = 5.0 NOVUS).
This will get interesting...
Will Peter Todd go out into the desert and burn a bag of VIDZ in a special ceremony?
