I started and still run ClickBook.net, a local business booking engine with 28,000 registered businesses and almost 500,000 users.
I, like thousands of others have become a defacto "forex trader" since BitCoin became so cool! It's an exciting new game which I see growing dramatically.
One weekend I decided I needed something to alert me when volatility in BitCoin changed significantly, without being glued to the screen all day.
