That might have been true few years back. Now people buy Bitcoin because they see headlines on Fox News and whatnot about "Bitcoin reaches new all-time high of $ XXXXX" nearly daily. I know it's a bubble when my totally non-tech relatives (the same people plagued by Ask bars) keep asking me where is the best place to buy Bitcoins or to find/recover their lost wallet.

Some people are speculating. Some people are believers. No one knows if it's a bubble. And you don't know the reason why people are choosing to buy.
