With no disrespect to the person asking the question, this is a stupid question.
(I understand he may still feel disrespected...)
I am sure it is less about the paper in this regard, and more about the title. But at the end of the day, no matter the commodity, it will come down to luck, a punt, a view that is held by none other on this planet than the person who is saying to himself, 'I am going down this road', in defiance of all other's point of unknowing view.
Choose a value-less commodity, buy when you're young, and hope with a view to being in the game for the long haul. Because if the answer to the 'disrespected's' question was easy to answer, then it would already be known, and people would already be acting upon it in hordes, to their own and each other's detriment.
It is the Unknown that is the investment. Choose.
