Until now devs has delivered everything and they will do in and for the future.
People currently don´t know what HPP is.... Check Zcoin... Currently at about 40 Dollar.
What does Zcoin really have more or is better than HPP?
Not really...

I won't make big jump guess but having what's on roadmap delivered surely establishes trust connection among the community; speculation on how much HPP will worth.
I don´t wanna say HPP will ever reach a value like Zcoin .
Own Chain, ZeroCoin protocol, HPC soon, Smart Contracts, ... this are only few thinks which HPP has or will have in the near future and will lead to a higher acceptance.
Go Dev´s Go!!!!
