You should wait and keep calm, the market try to find their pattern. BTC price too high to buy and too many news about btc that can give negative impact into it. This is the end of the year, everything could happen and we need to prepare about the risk. For safety, I suggest you buy btc after the end of the year and try to find the buy area using long period time. Have a nice day.
Every people has different target about their bitcoin.
For me now its time to sell and i will buy back in some low point because i am waiting for correction.
I will suggest you not to sell all your bitcoin. The best practice which you can do in this aspect is that you can sell few of your bitcoins and then you can re-invest that money into bitcoin again as well as you can make something productive out of that money. The rest of bitcoin, you need to keep them in your wallet as the market price of bitcoin will rise high in the coming days as well which actually means more profit.
