It depends on the perspective. Bitcoin itself don't have any coverage other than technology itself. So for some people, who can't see the potential of this technology, it's worthless. But, the Internet was in very similar situation at the end of second millennium. And in this case people had been talking about bubble too. And look where we are now.
It all leads to problematic question about what "worth" really is. For example, the value of gold is very contractual, it's only a symbol for many centuries. The concept of worth of the technology is still new and it's hard to compare it to such things like gold.
