I Guess halving is going to be around 2019. And this will be priced in 2018 not 2019.
People will start to go long on bitcoin before halving day and on halving day too many investors will be in huge profit.
bitcoin will give a surprised to its users on 2020 toady I check the price of bitcoin its price was very high and now its trying to make a record and a lot of it's users are waiting for this moment including me because I keep on hold a lot of bitcoin this year and I want to sell my bitcoins with high price and I hope that I will earn a very good profit from it so be ready for this end of year and get your profit from bitcoin and change your life.
