I predict that on the day of the halving in 2020 the bitcoin price will be $1666.
In all seriousness I think BTC price by the halving on 2020 will be on about $1000. I know some of you are expecting a lot of upside but it will really be disappointing for most of us because bitcoin at $1000 will show signs of being a little low for us compared to our very optimistic expectations. But that is reality and we must accept it fully.
