I have read in one media source, regarding the prediction of Bitcoin for 2019,
The media says that every 4 years the Bitcoin mining block will shrink.

If, judging from the results of the data, there is a big possibility that by 2020 Bitcoin could have been ranked: February 2020 - BTC $ 29,000
Starting from now: October 2019 - BTC16,000 $
It's still only a prediction,
The predictions are the same as we fish in the sea.
