ETH is currently hovering between 650 / 700 Euro as BTC struggles to break past $9000, possibly due to low volume and worry about a deeper dip. I feel that there will be a further climb before a final dip down to a new low (or at least re-test the low on the 6th Feb). From this low point it seems to me that the price will align with the pre-boom growth rate before climbing to a recovery.
I don't know if the price will bounce high and fast as bargain hunters re-enter the market, or if the recovery will be gradual over a course of months, but i'm confident HODLers should not panic. Personally I will HODL current stock and set BUY orders at potential low points during this period of volatility.
This is just my personal opinion, I could be wrong, but I look forward to seeing how this plays out.
