I think this prediction is too far, but if you want to try to find out the price of bitcoin in 2020-2021, the price can be more expensive than the price condition in 2018,
This is a prediction that will take 2 years to reach out and to know the future actual value so I even do not want to talk about the near future predictions because it is useless to know about the predictions we made. Look at the previous predictions you will come to that all were uncertain to the actual values so there is no need to follow predictions. However, the future of Bitcoin is going in the better direction with the passage of time.
