I have no faith in it to begin with.
I think it could still work as a currency, and I guess to an extent I'm grateful to the people investing in it for giving it an actual "value" people can put on it, but at the end of the day until a functioning economy is born from it that's any significant percentage of the amounts changing hands, it's all just meaningless.
As far as "faith" goes, "faith" to me implies the type of investor who thinks they can just grab a whole fuckton of them while they're cheap, and that they'll somehow magically gain value all on their own without anyone building anything from it. If you came to this conclusion on your own, you're a fool, and if you came to this conclusion because someone else implied it then you got swindled.
I agree with the first part; faith on my part will only exist when there is an actual economy that works in practice. Before then a number of occurences could happen that would render an actual working economy impossible, of which protocol failure and legal problems (which would target the exchanges) are two occurences that spring to mind. "The abolishment of the Federal Reserve and a return to a gold backed dollar" is a wet dream, but not even in a parallel universe is it a possibility.
