I give it an even chance of that happening. It should be remembered, however, that 1 BTC is really an arbitrary unit. People refer to mBTC (0.001), and these are currently worth $1 each. uBTC are a steal at just 0.1 cents. Still, as far as becoming a currency, I think the fact that bitcoin's mining curve is not at all related to adoption makes for a very volatile store of value. I don't know. Diamonds are nearly worthless, but we pay lots of money for them.
You may be referring to the Paradox of Value. If you haven't seen it before it's a good puzzle you might want to think about before following the link. Why are diamonds more costly than water?
Diamonds are not an investment's vehicle. It's the opposite: We cannot sell them once we bough them. "uBTC are a steal at just 0.1 cents" .. yeah as long some other people think the same. But the actual REAL line of thinking of everyone is " uBTC worth nothing, but it still can raise 1000 %" I'll buy it. And everyone is right. Not buying BTC at the moment is the dumbest thing to do. Even when you know it will crash, it can still raise a lot more. And everyone think he'll be clever enough to sell before uBTC goes back to 0,001 cents. It's a hope market.
