Price has dumped today so I will not sell them right now and will buy more bitcoins at this price as it will give me higher amount of coins at lower price and price can rise again and get back to $1200 level in next few days so at that time will sell some of them to get quick profits.
It is too early to buy back until you know where the bottom is. Sorry, price will not go back to 1200 anytime soon. I believe it will take months and we will see prices falling lower and lower every week. Sentiment has changed to a full bear market. Hodl your coins until next year and buy back very low, all will be fine.
But if it will go back to 1200 anytime then there is nothing wrong in buying them at this stage as price has gone below 1000 and if you think that it will recover soon then you should buy right now and sell them when it touches there instead of waiting too long.
