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.
At the same time, the global economic crisis is somewhere around the corner. It can have different effects on the market. Cryptos can fall along with all other stocks and stuff, or people can turn to cryptos to save their investments, and then the price will be very volatile and the network too busy, but it can really reach $100k. Moreover, there'll be halving in 2020, and halving is usually associated with increased prices. I just hope that the current run will not exhaust Bitcoin too much, and people will keep their interest in this coin even when FUD appears.
