Why start another gambling site? That wouldn't add anything new to the BTC community or expand it's user base...not fun or cool.

If I had millions to invest I would start a VC fund and be an early investor in BTC projects. With $2 mill to invest / $50,000 seed money per company = investing in 40 start ups in the BTC space.  It is a numbers game, the more ideas that get funding and see the light of day, the greater chance one sticks and solves a problem that changes the world.
