Unfortunately, BTC is far away of being a currency at all. It is used (as I wrote in a different thread already) much more like a commodity which is no good as a currency and a commodity have completely different purposes.

My only hope is that - despite the volatility in the market - shops, sellers and businesses will accept BTC on a wider and broader base over time. When that happens, BTC will go away form being used as a commodity and will be more used as a currency.

But that will take time. A few years at least (unless a real big player like Apple, Google, Paypal - you get the idea - would introduce it in their business model. I would live to pay my adwords with bitcoin!)
