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!
Indeed yes! When we say Bitcoin, it means
currency. I don't consider it as an investment or security. Bitcoin is meant to be used as currency, and if the price of Bitcoin becomes stable, we still got-
1. Currency which is purely decentralized.
2. Currency accepted in all countries.
3. Currency providing me anonymity.
4. Currency helping me to enter into deal with people from other countries at minimum time and cost.
What else we want!
