I don't believe that there is any insider of the market movement that will tell you exactly how the market is going to move after halving come next year, don't be JJ C of what called themselves about market movement of Bitcoin and crypto currency in general.
It seems like a monopoly is going to happen if there are insiders in the market that is planning to make their own trading signals. Well, i don't know what happens if people know this but i think there is something that can stop monopoly if ever there is.
In 2020, i think the price will be a little stable just like what happen to bitcoin this year.
