Popularization is only the first step, and the price of anything is affected by the relationship between supply and demand!
The price of BTC is also affected by the relationship between supply and demand. If it needs more than supply, btc will rise! On the contrary, it will fall and meet the laws of economics!
I try to tell as many people as I can in my locality, so that more and more people get awareness about cryptocurrency. When they realize the importance of bitcoin they will come to invest their money in it and thus the investment cap will increase. When bitcoin become popular among people the use of it will also increase and when people us it, it will circulate in the market and thus investors will be able to make good profits
