Bitcoin (as currency) is "backed" by usefulness:
1) for any shop in the world, it gives 3% more profit and a lot less fraud.
2) for any news-paper, micro-payments per article are possible
3) for 6 billion unbanked people, they can now enter the financial system.
4) for any guest-worker, remittance fees are reduced from 20% to zero
5) it's a rare asset and very easily transportable over the Internet.
There is a LOT more usefulness in it's Protocol (not the currency), but that's a waste of my time (as you cannot grasp it anyway).
HOGWASH... Ilogical arguments... I grasp... it's just stupid. Not backed by anything real... just belief and hope.
