In a situation where the project delivery is based on a fixed price in cryptocurrency, and there is an agreement to adjust the scope according to the value of the cryptocurrency at the end of each iteration, an incremental approach with a minimum viable product (MVP) is most suitable. This approach allows for the delivery of increments of value in alignment with the agreed price and enables both parties to assess and adjust the scope iteratively. It accommodates the volatility of cryptocurrency by allowing scope adjustments that reflect the currency's value at regular intervals, ensuring that the project does not exceed the financial constraints while still delivering value12.
