I'd buy 4 tickets on BitLotto where the jackpot for next week's draw is at over 120 BTC atm & with 99% of all money bet going to the winner that is excellent returns! If I then won (1 in 120ish chance atm) I'd let you know how I'll spend the prize - hopefully by next week it'll be enough for a BTF Single 
gamblor eh?
sure, with free money what's to lose
Well the coin you could potentially have.
but I'd only get the coin if he accepted my gambling proposition, I'm not going to make any other offer, but if he's quick (or the MM rolls over) I'd split it between BiLotto & this:

& if the gods of crypto currencies saw it assuming enough to run with I'd ask where he'd like the price to be stabilized - like for ever
& develop open source everything for BTC to be the new age's cash
& while it's an enormous long shot it could still be the most important 1 BTC donation in history ever
