First of all, I don't care Julion Hosp's predictions in that article because he showed us his capabilities as the president of TenX. lol
My personal opinion is that it will hit it's all time high (around $20K) in 2020 as we can see that the BTC adoption is happening day by day. Therefore, there is a room to go up the BTC price naturally to it's all time high in 2020. Hitting $100K also possible if there are lot of bullish news in 2020 from the key players like SEC. However, I believe the probability to hit $100K in 2020 is low.
That's too much of an expectation on 2020, you gotta measure how quick that would be. Someone who shall invest today can already own big condo after a year without even taking a risk. Price the last bullrun only stays at 20k, which means by the time it may reach that price people will soon sell again. Halving may have to happen first before it can go beyond that 20k
