If no one spends bitcoin and no one buy it but many people are mining it expect for price decreases gradually because the supply is increasing daily..
And more supply will come..
The price of bitcoin is always depends in demand and supply.. if bitcoin is in demand expect for price of bitcoin to increase high..
yeah, the price would most probably be going down because people would just hold and not do anything with their bitcoins, that would be really bad in my opinion
The price of bitcoin will be volatile either way. It's not just transaction from us consumers which are needed.
Just the whales are enough.
