For December 31, 2019, we got a different price with each method, $10,600 and $8780 respectively.
For January 31 to February 2020. We got a price target of $21,000 and $20,200 respectively, a relatively insignificant difference.
bitcoin is one of the first cryptocurrency that is very famous after reaching the highest price between $ 20k at the end of 2017, then bitcoin experienced bearish in 2018 which made some bitcoin investors frustrated and they expect bitcoin prices to recover.
And I personally am very sure that in the future bitcoin can still touch the price of $ 20k until the end of the year even though current crypto price fluctuations continue.
20k will be possible, with OP chart or not i think a lot of people will have same expectation. But what i use to be my note is maybe timeline that OP mention too short, will need big surprise to pump to that price for now. Maybe for people, if prediction about good price in future like this not like what you expect when time is come, as long hold bitcoin i think worth to still believe it will pumped, only need time.
