I think one reason is that many people in the bitcoin market are unsophisticated compared to your normal market traders.

But also, Bitcoin is an asset all by itself. You can't hedge it against other assets, like you can do with corn or tech. You can't easily short it. So, there's no "true" reasonable price range like with most assets, and no normal influences on the price. It's basically truly a bubble of hot air everybody is bidding on, except with the hope that the bubble will never burst, and be used as currency.
