I think what we witnessed in last december will happen again and at a greater extent. Don't ask me when, but that's a given.
Maybe you are right if we look at bitcoins graph last year it still can be dont by this year, day by day there is more people that give's interest on bitcoin but still we cant tell everyone that it will happen and you are 100% sure about it because no one knows what will happen.
Price won't give a fuck on whether it can be used everyday to buy stuff.
I think this statement is correct, until there is no demand added the price wont change or until there is no one selling below the right price. If everyone use bitcoin to fulfill their everyday need's it only affect's the circulation not the price.
