It seems very difficult for Bitcoin to break the price of 15,000 USD at the end of 2020 because it will only take a short time to reach 12,000 USD.
It took a lot of factors to penetrate 15,000 USD from Bitcoin, especially now that Bitcoin is experiencing a price decline of 10,500 USD.
Good luck at the end of 2020 for 1 Bitcoin = 15,000 USD !
