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.
