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.
Prove me wrong!
How many people in your neighborhood where you live hold or use Bitcoin, probably close to zero. And how many in your own family has recently paid for anything with BTC?
None. Because not a single person I know in my city even invests in general. Just consumerism everywhere. Does that make certain assets such as gold and stocks a failure as well?
You're making conclusions that bitcoin is a failure just because you don't know anyone using it. Even though you probably know well that Bitcoin is still a very new technology.
