When the price is low that is the right time to buy bitcoin and when it is high the right time to sell. This is the cycle of every market and we have to obey this cycle in other to be able to make money from the market. I agree with Novogratz on this and now is the right time to buy bitcoin and hold to sell at $9000. If you even hold further you will make more profits as I believe next year will be better than this year.
