I still remember this fairly clearly. That day, US Senate had a hearing and the price surged all the way to $900 before briefly crashing and China investors started to invest and accept Bitcoin then it surged past $1000. It was truly amazing I must say. Bitcoin was heavily regulated in China and it started to slide gradually. However, a few months later, Mt Gox became insolvent and the price crashed due to it being the largest exchange at that time and loss of confidence.
