It was certainly just one person buying up a few bitcoins here and there. Now we don't see a meaningful continuation, so unless that person decides to buy again, we are likely to continue trading sideways over and over. Personally, I wouldn't be surprised if we went back to below 7k in the coming days. On the other hand, I have a feeling that the growth may be just around the corner as people have calmed down a little after the emotional roller coaster we've all been through during the first quarter of the year.
