Pegged Pricing Model (PPM)
The concept of using Vulcan token to redeem for Vulcan's products and services is straightforward. Vulcan token holders may redeem their tokens for a dynamic value determined by the fiat exchange rate.
For example, if the ICO price of Vulcan token (VCN) is 20THB, the Edio book price of Vulcan is 250THB. Edio book can be redeemed at 12.50VCN by Vulcan token holders.
When the price of the Vulcan token reaches 40THB, the number of Vulcan tokens required to redeem one book will be floated (book price/VCN market price) to enhance the purchasing power of Vulcan token holders. In this situation, 6.25VCN is all that is required to purchase one Edio book.
On the other hand, if the price of the Vulcan token falls below the ICO price, the amount of Vulcan token required to redeem one Edio book will be tethered to the ICO price in order to maintain the purchasing power of Vulcan token holders. For example, if the price of the Vulcan token falls to 10THB, instead of using 25VCN to acquire one book, the pegged pricing mechanism will allow Vulcan token holders to redeem for one book using 12.50VCN. Or, to put it another way, this mechanism locks the Vulcan token's price at at least 20THB.

Buyers benefit, sellers suffer?

At first look, the pegged pricing model may cause sellers to lose revenue when we convert back to fiat currency. However, a closer examination of the mechanism reveals the inverse.
When the price of the Vulcan token falls below the ICO price, buyers can redeem Vulcan's products and services at a lower cost than if they paid in Thai Baht. This approach is designed to increase the demand for Vulcan tokens on the exchange. That is, users can use fiat to exchange Vulcan tokens for products and services at a lower cost than acquiring products and services directly using fiat.
As a result of increased demand for Vulcan token on the exchange, the price of Vulcan token will eventually rise above the ICO price. The transitory price dip below the ICO may result in some revenue loss and a flattening of the profit margin, but more selling volume will compensate for the narrow profit margin after all.
PS. This pegged pricing model works well for high-margin products and services such as AI as a service, digital products such as ebooks and music, and so on.
