Does it? Why? I mean, people currently want to buy it, but then in the early to mid noughties people wanted to buy securitised junk mortgages; simply having a potentially temporary demand does not mean it has an _inherent_ worth.
If anything, it has less of a worth than before, in that its "success" has made it largely useless for actual transactions. Look at the current costs to actually get anything through; it's stormed past SEPA and threatening to hit Western Union levels of expense (it's already exceeded Western Union and friends for small transactions). What is it _for_?
