In the beginning Bitcoin was only an idea. With a value of a fraction of a U.S. penny. This was in 2009.
Then in 2012 bitcoin gained popularity on the internet and gained its first publicized value of $13.28.
This was the first recorded value of Bitcoin. Now lets see how Bitcoin progressed over the years
2009 $.0003
2013 $13.28 44266.67X gain in 4 years
2014 $770.52 58X gain in one year
2015 $315.42
2016 $435.82
2017 $959.15 1.24X gain in 3 years
2018 $6355.70 6.63X gain in one year
2019 $? 10k, 20k, 30k, 40k, 50k
2020 $? 60k, 70k, 80k, 90k, 100k
With these mathematical statistics it is sure enough that Bitcoin will be rising to the 100k mark within the next couple of years.
The 10k is not impossible as it already reached it but psychologically if it breaks that price it will be another hype so might get to 20k again if that happens. We all hope it reaches the 100k level be it in 2020 or after.
