I am sure, although bitcoin prices remain stable, it will become popular. Well, bitcoin prices are higher than other altcoin prices. So of course bitcoin hunters will still look for bitcoin, not as an investment, but as money will be made in cash.
I doubt it. Few people use bitcoin only because of anonymity. Many bitcoins attract only a steady rise in price. Bitcoin will lose a lot of users if this happens
It is true that the bitcoin users thrive for the use of bitcoin as a trading material and less as a currency. More volumes are bought and sold these days and the prices are bound to rise. As more people start to use the coin and buy it the prices rise. This attracts traders to invest in it and make profits when they sell it a lower prices than that what they bought at.
