Price predictions vary between $0 and multi-million dollars, depending on who you ask. The reason there is so much variation is that essentially everyone is guessing.

That said - if you look at the all-time chart for bitcoin on a log scale, then a cyclic upwards movement of higher highs and higher lows becomes apparent... so predicting based on history, and that we are just coming out of the dip stage, then the price in 2020 will be somewhat higher than now.
