I think bitcoin doesn't follow its path in 2017, and I'm not sure whether bitcoin will be high in December, and bitcoin still needs more time for it, my estimate is that bitcoin will rise in 2020 or 2021.
His name is also a prediction, which can be true or even wrong. if you look at the graphics, you certainly cannot be sure that you will be equal to 2017, so also I am not sure that you will increase 2020 or 2021 like the opinion above. now if you see bitcoin it seems like you want to climb, but will it happen the same as 2017 !! no one can be sure but as someone who is involved in crypto clearly wants bitcoin to climb up to the best price, because it is my dream.
