> What is driving the value of a bitcoin?

No one knows, maybe some have same theory of value and that's why there is speculation? I see nothing special in bitcoin, it is just one of the numerous things that the market tries to value. If the market is only speculation the value should go to zero in the long term. If there is some value in addition to speculation, the value should be non-zero - and it is left to the markets to decide, what the actual value is.
