I would do what most of the people here will: 1- withdraw most of it to an offline wallet 2-keep around 2-3 bitcoins for trading it with altcoins as well as any investment opportunities as well, perhaps giving few bitcents of it as well "to spread the sharing 
"
"I would also cut it into 2 parts from which 1 part i would withdraw and use on myself and the other part i would invest in trading because i feel i can make good profits in trading altcoins if i have a good enough capital like 5btc or so.
