Who would know what to do with that much money? I'd go on a big vacation with my family, go to Minecon 2013, buy myself some kickin' duds (MAXIMUM SWAG ACTIVATE!!!) and probably save the rest for whatever comes up.
Invest 80% and spend the rest on whatever I damn well please (including, but not limited to, moving to Western Europe, paying the uni's tuition fees and maybe in a long stretch moving my family over as well; also fancy clothes and a nice home)
