We must agree that bitcoin and other crypto currency could not grow in price continuously and without significant fluctuations. Their price has fallen sharply, but we know the reason and this reason should be eliminated in the coming months. Therefore, nothing unusual happened. Now it is necessary to prepare for further raising of the crypto currency and therefore buy it at a low price.
I think it depends to you if you want to keep on buying bitcoin but I think it a good idea to buying bitcoin because having a lot of bitcoin is a chance to become rich in the future. As of now the price of bitcoin is keep on increasing so that even the price was totally high you must still buy bitcoin afterwards you must hold it.
