The average consumer is not going to use a currency that jumps around in value, takes sometimes hours to confirm a transaction,
cant be used other than buying things on the internet because of the transaction times, and many of the other issues currently facing us right now.
Face it. Bitcoin is a novelty. Until a lot of these issues are resolved, its going to be magic internet money for kids to play around with
I suspect people were telling basically the same when the Bitcoin price had been only around a few cents per coin. If anyone was saying that Bitcoin would be worth over 1k dollars, that would most likely have been considered as pipe-dreaming (or wishful thinking at best). Personally, I'm more inclined to think that now when Bitcoin has established itself the chances of it going way higher are more real than they were when one bitcoin had been worth only a fraction of a dollar
Ultimately, this is no more than the limitations of our mind
