For some investor's that had bought btc when it was at $20K price value, definitely if they will sell t now, off course they will surely loss great amount of money. However, people are not that dumb wherein they would sell in the situation where it is a bear market instead they should have to hold it still and perhaps wait until such time, bitcoin could already recover from it's great dip. I personally believe that bitcoin will recover in due time and as to when, I would have to speculate that bitcoin could make a bullish run in the last Q4 of 2018.
