For bitcoin to be used as a store of value and a medium of exchanging for goods and services, It must be stable like others currencies. For the past 5 to 7 weeks now bitcoin has started to develop that characteristics and that is a big sign that both online and offline retails and wholesales business will started to used it very soon. I believe that in blockchain technology we are getting closer to what the founders has in mind.
History shows you are wrong, people love the volatility and the money they can make in it, just look at the stock market, if a stock is not moving wildly many sell their stocks because they do not want to waste their time holding stocks that do not move, and the same is true with bitcoin, when was the interest in bitcoin at its highest point? When bitcoin was reaching all time highs every day.
