The headline doesn't mean anything. Primarily because I don't know what you mean by "invest".<p>I'm doing a PhD in Chemistry. My personal investments are (1) spending money to go to conferences (2) buying semi-respectable clothes I wear once a year (3) buying food that won't destroy my health.<p>I haven't got spare cash to get in on the ground floor of whatever cyberspace social hack that happens to be popular somewhere I don't live and is valued at a price I'm pretty sure is completely imaginary.<p>Your first move should be to hazard half a guess to your own question.
