There is a downfall in the price of bitcoins in recent times so I will surely not sell my coins and hold it longer until it doesn't recover once again and this is low price to me so I will surely prefer to buy some coins at this stage and keep it safe in my wallet as I am sure that price of bitcoins will hit $10k in next year and that would be the best time to sell my bitcoins at higher profits.
It is a good option if you entered bitcoin when the price was high and you could not sell off at a profit,never sell off anything at a loss and since you have the money to collect the coins you should go forward with it and average your loss and go for the long hold,buy and sell depends upon the entry point and the profit you are in.
