Well, my gut feeling is that it is getting further and further away from regular Joe in the street, and it may be eventually just getting concentrated in the hands of the rich classes as a store of value.
You know why? Because the regular Joe in the street isn't likely to take part in new technological inventions. Especially when they don't even know what a certain technology does in the first place.
It is silly to think that a regular joe would use bitcoin now.
Bitcoin is still very restrict. There are people who use it to invest/trade and some others who receive it from services done in the internet (blogs, webs design, coding). Very few people use it to buy stuff, as there are very few places to use it.
Maybe in a few years we will see big retailers such as Amazon/Uber/etc using it. Then the regular Joe might be interested.
Personally, bitcoin is still mostly useful to buy/sell stuff in the internet, specially when dealing with people from foreign countries. When I am face to face I prefer to use Visa/cash, specially because of long confirmation time.
But I could buy a TV in the web using bitcoin, it would be nice.
We will get there some day, in a few years.
