tl;dr = bitcoin will probably fail.
The author uses Flooz as an example of a failed online currency. Flooz was based in New York City. Flooz was a dotcom, bitcoin is not a dotcom. The company was investigated by the FBI. Bitcoin is decentralized. The FBI has no jurisdiction over the global economy. There is absolutely no comparison.
I keep hearing about this comparison of Bitcoin to failed digital currencies, and specificly Beans and Flooz. Yet I had never even heard of either of them before Bitcoin. I can't see how either of them could still compare at all, did either make a market cap of over $100 million?
