I was in the middle of programming an iPhone app when my computer took a shit, this was back in February. I was making really good progress, but now I can't work on it because I need an Apple computer.

I'm getting fed up of not working on this, but I need $800 worth of Bitcoins to buy a new laptop on craigslist (since iOS apps can only be developed on Apple computers). I have a bond of about $2,000 waiting for me in a few weeks, but I want to work on the iPhone app now. I will return $850 worth of bitcoins to you for the risk and will give you the first $150 out of $300 of my profits once I release the iOS app (if I make any). So if I make $50 in the first week of release, I give you $25 etc until it goes up to $300 if that makes sense.

Keep in mind, lets make it easy and say Bitcoin is worth $100, and you give me 8BTC ($800), and when I get my bond money Bitcoin jumps up to $200, I will give you 4.25BTC ($850) back. Similarly, if the price instead drops to $50, I will give you 17BTC ($850) back.

I have never done anything like this before and if anything seems sketchy feel free to ask.
