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?
The price will grow till the bubble go off. Plain and simple. Aftter that< i think, we will have another coin which is going to be leader. Not bitcoin. We now see bitcoin leading because all the newcomers think that all crypto is bitcoin. They don't know anything about alts, so invest in btc only. In future situation is going to change.
