I love the concept of Bitcoin. I believe the Internet will redefine currency as we know it. I hope this helps the Bitcoin community to develop a currency that's really resilient to attacks.
But, is it possible?
Nope it isn't. This is because of the block chain technology and the algorithm that bitcoin posses. So in order to hack and duplicate a bitcoin would be totally taxing. I can remember an article I came across where is mention that in order to duplicate 1 bitcoin would cost you more than the current price of bitcoin. And during that time bitcoin was priced around 10000 USD.
