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!
Of course i will, as long as i can earn them. I have never bought any bitcoins with my own money but i have been earning them from start till now, and for me no matter if the price stays stable, it is not that i don't like it when it goes up but as i'm not buying bitcoins so it wont be a problem for me if it does not go up, but i should just have a way to earn them.
