Well, I think it depends upon the user if he will perceive it as a security, currency or as a commodity. Upon reading the news article you have attached, it states that most Bitcoin enthusiast, perceived Bitcoin in terms of security which I do understand why that makes me think I belong to that perspective but upon reading the article Bitcoin as a currency which is a perception of SEC, I found it reasonable that indeed we treat it as a currency which is obviously why we call it as a crypto currency right? The last is commodity which is also right, so no matter what you perceive Bitcoin is right. No wrong perception because all depends on how you see and treat it and it must not be a case of debate for a long term since we have made it to have a different registry that is basically based on how different groups of people sees it and categorized it.
