Acquired a lot of bitcoin and could use some advice!

Hey guys! Fairly new to bitcoin so that's why I'm asking for some help. I'm a high school senior and I love to write, so it was exciting when I found a little gig to write weekly articles for a small website. The owner paid me in bitcoins based off the views, and in my month doing that I made around .5 bitcoins (Only wrote a few times a week).Here's where I obtain a ton of bitcoins: I didn't feel like going through the hassle to turn the btc to USD (which I'm sure is pretty easy), so instead I decided to do something exciting with it. I made a very large parlay bet online with the bitcoins on NFL games. I'm not much of a gambler, but I somehow was right about every game I selected. I now have 48.3 bitcoins and while that may not be a lot, I'm freaking out on what to do. The money is still on the gaming website in my account, but I obviously want to take it out.Should I hold onto the bitcoins on my computer and hope the price goes up? Or should I put it all into USD (how would I even do that?) Or maybe do half and half?If it helps, I have no bills or monthly costs (like I said, I'm in high school).Thanks for the help! via /r/Bitcoin http://bit.ly/1Vvs2CP
