I think most users are involved in Bitcoin not because they belief in the technology, but because they hope the price will go thru the roof. So let us say the price would be at $900 for the next 50 years.
Would you still use and buy Bitcoin or would you leave?
EDIT: Poll added!
I think so, many people only care about the price of Bitcoin, waiting for price increases to benefit, they not interested in technology of Bitcoin.. This is unfortunate for those who do not care about it. In years to come, including the price of Bitcoin is not stable, I will still using and trading it as now. My favorite thing in Bitcoin is technology and its features, price is only part. Modern technology of the new Bitcoin is a constitutive element of its true value. 900$ for the next 50 years, it's not too bad, I thought it was a good price and suitable. If the Bitcoin price stability over years I think there are still a lot of people use it, but I think that prices of Bitcoin will not stabilize, maybe it'll be a bit of fluctuation.
