RE: Holozing: ZING Market Value & Alpha Vials - Updated APR and Break-Even Calculations (ENG/ITA)

Yes if Zing drops to zero it means you can no longer trade it for Hive and it's all been extracted.
LPs take a big risk and only get half of the reward if number goes up... which is why APR on the LP needs to be relatively high to make up for this.
