Now it is too risky to sell because we do not know how far down the bottom is and if this is the bottom you might get priced out. The time to sell was a few days ago and many of us missed the boat. The whales coordinated a big attack to all sell off at once across the board. Now if you have any spare fiat cash, now might be a good time to purchase more Bitcoin, Bitcoin Cash, Etheruem and some of the other big coins that have fallen drastically in price over the last few days.
Yeah I think that if you have invested in bitcoin and want to make money through your investment then wait for some time. There is no need to sell your bitcoin on low price. Many people say that 2018 will be the year of bitcoin and the price will be more than 30000 dollars, then why some bitcoin holders think that they may lose more if they hold bitcoin for some more time because the price is decreasing day by day.
