Most people are relying on faith, which in my opinion is something they should not do
Faith might be called as speculation, and that's what bitcoin is based upon.
So, if relying on faith is not correct according to you, then 1000 USD would not have been possible before.
The 1000 USD before was mere manipulation, and see what it got the investors at that price to. They are yet to get a ROI, I am not saying 1000 USD is not achievable, but I think it is not yet this year. I can see Bitcoin closing at 750 - 850 range this year , probably some set back at 700. If bad press kicks in we can see sub 600 USD or way less.
