Bitcoin has established a new trading frontier. Likely due to the over half dozen Forbes Midas winners supporting it's market development.
One of my favorite tools for discovering just who is making a new market is: Muckety Maps www.muckety.com/Bitcoin/5098400.muckety
A quick dig into the interactive map will show you the massive support readying for this new market. Including Google, Andreesen Horowitz and the Winklevoss twins.
The market is currently very immature; similar to the very first weeks of Currency Trading. It is however quickly forming into a great opportunity for experienced traders.
I have bought and sold quite a variety of them to work up a "Proof of Concept" trading system. The only coins that do well are the ones that have good support, solid marketing, and a smart foundational concept.
The rest simply die on the vine like a tired penny-stock scam.
