Dutch auction

Thanks to the dutch auction there is a ZAI bronze, a ZAI silver, a ZAI gold and a ZAI platinum permanently on sale.

The prices of these ZAIs are defined by the average price of eggs on sale in each nursery with a multiplier. These coefficients can be modified by vote of the DAO* in order to balance the game.

ZAI type	Multiplier Coefficient
Bronze	2
Silver	4
Gold	16
Platinum	100

The price of each of these ZAIs drops by half each day, and with each sale a new ZAI is put up for sale at the average price with multiplier.

Duration of the sale	ZAI price
Putting on sale on the marketplace	200
D+1	100
D+2	50
D+3	25
D+4	12.5

Example: the average of the bronze eggs is 100 BZAI => the bronze card is on sale at 200 BZAI, at each block the price goes down, 24 hours after the sale of the card, its price is 100 BZAI and goes down as long as the card has not found a buyer.
