Everyone talking about how the system will perform, but i'm more worried about token's utility. What benefit will NAYA have ? And will them be enough to have sustain the toke price ?
from what i see in here, your worries is the easiest part to be reached and obtained. once that all the process os asking for a software inside the Builder, the NAYA token will be staked by the Smart Contracts between customer and developers. and developers need to have NAYA tokens as well for being able to accept an order for a development of a software/app/website. and considering that the Engineer.ai has just as software developers around 26000 persons, you can easily understand how the value of the token will be grown. and this is just for the beginning. once that all of the other customers get to know how easy and cheap is to get thing done by engineer.ai, they will come and order through the Builder and the AI. and since that the Naya tokens have a limited supply, the value of those will grow. and here is were the investitors on the ICO and get some profit, if they do not want to use the NAYA tokens for getting something developed inside the Engineer.ai platform.
i can go on, but i thing it is enough. do you see it now?
There are other options other than NAYA to pay though. Though ofc using NAYA will yield some extra benefits
Engineer.ai just needs to ensure they explain themselves clearly to their target market accordingly.
