In my own personal opinion, bitcoin could really get back it's price up to 20k USD, but not for now it can't because bitcoin is still recovering it's price from it's downfall in the year of 2017. I think bitcoin could reach it's 20k USD price in the year of 2021 because bitcoin halving will happen in the starting year of 2020.
Almost all crypto users say that the price of bitcoin will reach $ 20000 by 2020, and they say that because of Good information support. although like that, we don't know exactly when the price of bitcoin can reach the price of $ 20000 by 2020, but many people analyze that the price of bitcoin will arrive at the price of $ 20000 in May 2020.
