The price volatility is unpredictable since the beginning of bitcoin operation. Also bitcoin price doesn't established a stable price at $900. It just stays around that range but only for a few days only if you will summarize the weekly or monthly chart view.

If this is a downtrend or will it be back again to price increase doesn't have an accurate answer. Just take out those extras arrows and began targeting and purchasing those bitcoin at cheap rates to considered if you believe that price will back again and passed it's ATH.

No room for too much coffee when there is a sudden price rally whether to increase or decrease.
