People are just paying attention to market prices to make a quick buck. They're not into Bitcoin because they believe in it. I'd say utility goes above all else. Satoshi made Bitcoin a peer-to-peer electronic cash system without middleman, and so far, it's been working as intended. We let "Wall Street" get into the revolution, and now the majority considers Bitcoin an investment instead of a currency. While it's likely BTC will rise in price over time, we should expect the Blockchain to become heavily-congested due to increasing mainstream adoption.

Things aside, I believe it's still early to get into BTC, especially when its market cap is a lot smaller than Gold's. There are many people around the world who haven't used or heard about Bitcoin before. Once we include everyone in the system (or almost everyone), BTC will never be worth current market prices ever again. Maybe you'll get lucky by holding onto it before this happens?
