Your question seems a bit illogical.. ( Or too logical  )

Ofcourse the price is going to be higher if more people use it. Less supply (people will keep losing coins over time) and more demand/people that want to have/use it.

I however am interested in seeing how Meltcalfe's law works with cryptocurrencies, ( defining the value of seomething based on the amount of users it has). (If it is applicable at all here.)
