Theoretically it is, being that the nature of bitcoin is highly volatile, but come to think of it, this is just a part of bitcoin's value getting a correction, if we can still remember, way back in december, there were people who are not investors that came in to play, they have bought bitcoin at a higher price, and those who had bought if at lower price will normally just take profit, leaving the weak hands behind, thus a drop in the price of bitcoin, and now we are clearly seeing the correction in the market, and that's the reason why the price is not going up by 50% or going down by 50%.
