I would like to think I would do the following
Spend it all on cocaine and hookers.

Or waste it thus:
1) Hold 40% , wait for the Litecoin hardware arms race to start. Its inevitable and just hope your following the right company to get your order in fast enough for the 1st batch
2) Invest 30% into LTC and hoard in hope of increase when MTGox starts to trade them, if my head is in the right space with this then you could get to sell them @ 4 to 5 USD, I dont see it going much higher.
3) Invest 30% in mining shares
4) After turning your 40% around and hopefully making a profit I would re- invest it in whichever option 1 or 3 you know prefer or see making more money.
