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?
Not forever because we don't know what happening to the future and in the first place not always increasing because bitcoin value was depending on the economy of each country and value was not be stable also just because of the flactuation someting falling down and sometimes rising up so that is why we dont know if in the future or you called forever rising up.
