I think the volatility is still a major question for a lot of folks. They may want to own it but given how much the price bounces around they dont think it is for them. That said, this is easily solved by what is known as "position size". A person can allocate a smaller amount if they dont feel comfortable with a lot of volatility in their savings. In addition, focusing on bitcoin as being long term money instead of "get rich quickly" helps weather short term storms in pricing.
