Since the total number of bitcoin is fixed, so the value of bitcoin will keep grow, and it's price will keep grow also. So will there a price cap for bitcoin?
Yes Op, I believe that as the demand will keep on increasing day after day so shall the market value of Bitcoin keep on increasing. But remember that Bitcoin market value Will get to height where its value will remain stable and then , other altcoins will start getting more acceptance world over and that will create a strong competition among them.
Yes, It is the law of market that when something increases in demand and more and more people are showing interest into it, the value of that commodity increases too much just like the value of bitcoin at present. There are maximum chances that bitcoin will become the most expensive asset of the world in the future when it would be accepted worldwide. Soon it is going to be legal around the globe.
