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.
I totally agree with your idea, if only bitcoin (the most used crypto) would be more stabilize it would be much easier for it to be traded in such a worldwide basis, the most problem right now is that as much as they want to use it it will take so much time to calculate and reanalyze their product every time bitcoin change its value.
