Bitcoin: store of value. 
Yes store of value and medium of exchange just like a baseball card.
Except more durable, more fungible, more divisible, more easily transportable, harder to counterfeit...
Stop calling it currency 
What's it matter, anyway?
Because if you can realize that bitcoin is not currency because it is not a UNIT then you can realize that the US dollar is not currency because it is not a UNIT.
That is what Ron Paul is really asking Ben when he asks can you define a dollar for me. He is really asking what is the UNIT called a dollar equal to?
Okay Einstein, why don't you enlighten us and give us an example of something that is a currency?
bytes, kilowatts, the dollar in 1970,oil, metals they can all be currency. Because they all can be mediums of exchange, stores of value, and a UNIT of account.
Bytes and kilowatts aren't scarce. The dollar in 1970 was just a piece of paper that was supposedly backed by gold. Of course Nixon let the world know in 1971 that the backing of paper with gold can be undone with the simple stroke of a pen. Oil is a consumable commodity. Precious metals are the only form of sound money the world has had before Bitcoin, but now the bankers have scammed the people into using their paper and managed to hoard most of the gold for themselves. That rules out everything on your list. Please try again.
