Will someone post a book review for me?
You make a $5 profit
1) I'll pay you $5 worth of BTC right now
2) After you receive your money, you buy the book ($5) on Amazon.com
3) Later tonight I'll send you a review to post.
4) I pay you another $5 of BTC once review shows up (tonight or tomorrow)
I only have enough BTC to pay one person
I am using the Mt. Gox exchange rate ($5 = .051 BTC at this very minute)
I did this previously (
