I think it is a normal thing, after all the price stability is determined by the transaction flow of the user, i think because there are no large buy or panic sell, so the bitcoin price in a stable period, so don't too worry about it, there will be come the time where the price will keep on rising
Yes, it is a normal thing because of corrections with bitcoin price and seller and buyer waiting for the next news. But I think bitcoin price is now starting to move again. Seems there new batch of investors to push bitcoin price higher than the previous week during the correction period. I would expect bitcoin at $850 at the end of 2016
