A bitcoin currency exchange/trading platform site headquartered in USA - Atlanta, GA.
CampBX is a platform where you can buy and sell Bitcoins for US Dollars in real-time using advanced order-matching algorithms. Any buy or sell order that you place is matched against a database of other orders. If a perfect match is found, a Bitcoin-to-USD trade is executed instantly. If there are no matching orders at the price you specified, then your order can remain open for up to 31 days. To maintain fairness in trading, CampBX have taken a purely-platform approach and they are never a counter-party to any trade.
This platform was designed from the ground up with stability and security as top priorities, and became the first Bitcoin website to obtain Payment Card Industry (PCI) certification and the McAfee Secure seal of confidence on June 28th, 2011.
CampBX is also the first Bitcoin platform to bring advanced features like Margin Trading and Short-selling, and have several more innovative features in pipeline.
There are no fees required to open a CampBX account.
