I don't think common people "should" use Bitcoin right now, it's very complicated for most, specially women and not tech savvy people. I don't want to sound harsh but that's my experience. Also to be honest everything can be done via credit cards or paypal, there's not an actual need for Bitcoin for them. Privacy is an illusion and credit cards have insurance, there's no risk and they are instant.
Bitcoin strengths are other things, like its unique technology, disruptive ideas that can be applied or used in the future but because of price volatility and difficult to get a hold of it hasn't found a niche yet.
