Does the customer will have only one payment option? I mean you will accept only MRDS tokens for learning network power service, or you will accept also other cryptocureency as well. And could explain what do you mean by saying that lowest price based on a perfect market. No humans setting prices for ML services !
I am sure that there will be several payment methods. I believe that the project developers are solving such aspects at the very beginning of the project development. I wonder if there are any other payment methods available
