I think bitcoin will be "Commidity" especially for those investors, rather than they buy Gold or house and lot they buy bitcoin as a commodity because they believe that someday it's value will be great.Also this is a digital currency and this is easy to carry in life or in bussiness because your life will not be dangerous rather than Gold that your life would be dangerous because I think if the holdapers know that you have Gold , they eventually hurt you to get that gold.
