Hi and thanks for joining.

The short answer is no. The merchant exchange conract does not operate with a fixed Token/Fiat rate.
We do not fix a USD rate. Instead the merchant issues an invoice to us for the sum Fiat+VAT value of goods being sold for Tokens.

This is totally different. And it is only likely to apply when Token price lowers significantly. Even then merchants are still insentivized to hold their balance. Anyway this is our merchant investor protection model. It is necessary as we have to address price volatility concerns of potential acceptance points.
