Payment could be made in tokens and fiat. However it will be displayed and the only possible way to pay - in tokens that will be converted into TED tokens. Over the coming years, TrustED will plan to completely embolish the fiat pairs on the platform, and only have the TED Tokens as the functional currency on the platform. The fiat addition is included for the initial stages whilst the platform pushes for further adoption.
Proper implementation. In addition, for the average user it should be as easy as using a regular application. Cryptocurrency and the blockchain are not yet familiar to many, so ordinary money and ease of use should be.
I think it is very good that will be used not only tokens but fiat too, It will make the platform more comfortable for the users becouse not all the people know how to use cryptocurrency and tokens and in some countries cryptocurency prohibited.
