I think that people are not yet ready to buy something or sell for crypto-currencies. This will all become real when there is not such a strong volostiness as now. Now it's better just to be engaged in speculation as well as doing everything.
Better to be engaged in speculation? Definitely not. I noticed this year that more people are actually utilizing Bitcoin as currency, and the few people I know and conduct business with, some times ask me if I don't want to buy anything from them with Bitcoin because they badly want me to pay with it. I have never seen this before and it makes me excited because this is just the beginning. I would gladly pay with Bitcoin for their stuff but I'm not going to buy things that I don't need for the sake of using Bitcoin as currency. Instead I some times give them smaller chunks to experiment with, all to make them feel how powerful Bitcoin is.
