Yet people still bought computers knowing full well they are going to be cheaper in a couple of months. Why? Because they needed them. Same thing with Bitcoin. Of course, you won't be buying stupid stuff you really don't need. And you know what, that's a very good thing for the economy, because it will make people very responsible when it comes to buying things and investing their money. Bitcoin is an ultimate cure for consumerism and excessive spending. Economy as a whole and people in it don't really profit from investing into useless hole digging, even though it may look good on the paper.
