Yawn. Fraud is easy, no matter how you define it, stealing a few bitcoins on the other hand merely takes a finite amount of resources. You're essentially a troll. What you say is true but double spending a few coins (your maximum return is 2x) would take hundreds of thousands of dollars and a lot of luck. Duplicating paper money requires an inkjet printer with good registration and the common sense to separate the eruion constellations into separate layers. It's not rocket surgery, and once the source file is made it can be replicated at any copy shop. Its vanishingly unlikely you haven't accepted a counterfeit bill, and its vanishingly unlikely a bitcoin could be double-spent beyond seven blocks. Give it up. Bitcoins may not be a sound investment but they're far more secure than cash for both parties.
