Bitcoin will rise again is what everyone expects, but we still have to be cautious, because now the crypto bubble is obvious, it may need to wait for the bubble to completely disappear before Bitcoin can really rise.
I beg your pardon, but what do you mean when you say about the crypto bubble? I am sure, Bitcoin will grow in 2019 again. It might not reach its highest price (20 thousand dollars), but it will gain really a lot.
