I think the price is all that matter. Peace
It is the only big reason why traders like to trade on bitcoin vs altcoin and bitcoin vs fiat. However it has a downside, if the price falls too much people may convert all bitcoin to fiat and stop using bitcoin. However the chance is very less.
you are right, as the price gets bigger more and more people get to know about bitcoins and they buy into it
Bitcoin became very popular when the price shoots up 88x up to $1200+ in 2013. If not for that bitcoin wouldn't be very popular today.
