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!
You are right at some extent but here most of the bitcoiner doesn't dependent upon the price fluctuations .
As the trading became a tedious job to make profit , so fluctuations in the bitcoin price became a profitable thing for those some bitcoin traders .
But opposite of the price of bitcoin fluctuations , I want price of the bitcoin remain constant because some bitcoin trader don't want disturb in price because they have huge difference between the buying and selling price .
Secondly in the signature campaign the price changes if the price of bitcoin increase but when the price get lowered then they never increase the bitcoin amount for the per post , that is a thing which is annoying .
