The question of OP is related to ...
I see the dude will earn some profit.
If he convert this profit in bitcoin or beer - who cares?
And who have about $70 000 - there are better rates, but that is about adult business.
I don't want to argue about this but your reply to him seems pretty much off-topic and out of the scope of this discussion so I've pointed it out.
OP, why not try buying an account with a high ranking in here and then do some forum posting? Or do services to others which they might find useful. That are some of the ways I could think of for you to 'invest' involving bitcoins.
