before year is good sell all everything your balance bitcoin
and then buy back again in early month 2017
because in end year until early month bitcoin price trend in down price
Lol how do you know that the beginning of the year prices will fall, I do not think there will be people who know that the price of bitcoin will drop or rise in the beginning of the year. if you want to sell all your bitcoin make sure that the highest price before the price falls, while the current trend of rising prices of bitcoin continues to happen
