Just wondering why users will choose your service instead of similar service that use fiat as currency. What makes yours unique and better? Was thinking that you'll need to make it crypto-friendly to attract cryptocurrency fans who prefer not to deal with fiat-based services
If we have this kind of thinking in every cryptocurrency then basically all cyptocurrency are useless at all since fiat currencies already exists but this is not the case now as we are seeing more and more crypto based projects on already existing businesses and application. On the side of parking owners accepting or availing their project for their parking spots will just give them another payment option which new users might be interested in using rather than fiat. It's up to the project developer to decide how this users will use their crypto more rather than the fiat currency they have whether its through loyalty points or giving a much better service compared to the already existing ones.
