What is happening in the market for Bitcoin in my opinion can be explained easily if one considers how the market is still small, but how big are the interests against the development of a peertopeer coin without masters and with no state control. If i was a banker, a federal reserve, a credit card owner, paypal or a gold reserve owner for now I can invest very little money to cause a depression in the bitcoin market. Mtgox has a volume of some hundreds of thousands. I can easily buy bitcoin at 20 and sell at 15, rebuy at 15 and sell at 10. I will lose maybe some million dollars but this it is very very little in comparison to what I might lose in the future if bitcoin establishing themselves as digital money currently used. Some day ago there was Bilderberg Group reunion, i think some of the speech were about bitcoin and their risk for the establishement. Now someone is working on bitcoin… Could this stop the bitcoin economy? Surely a big deflation was a big advertising for bitcoin and now depression can stop enthusiasm of some folks but bitcoin are still a great idea and i hope there will a future for them because we all need their freedom.
