To be clear, VIS is minted (created) through players placing inside the top 3 when racing, there was no IDO for VIS and no VIS was ever "pre-minted". VIS is burned (destroyed) through the Breeding model (and other VIS sinks in the future) outlined later in the whitepaper. Our goal is to create a reasonably balanced mint and burn ratio while avoiding micromanagement and over dictation of the ecosystem.
