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 do agree . im using bitcoin because i know that the price is unstable like there are time that the price will go high because that time we will earn a lot because of volatile price. if the price would be still in $900 well im using it not because of the price but because i earn from it and i can use it in real life or to buy some stuff online with the payment of bitcoin
