You are right, if the situation continues through 2019, BTC will drastically lose its support. It is reasonable to expect from the people to be patient through the first couple of months of 2019 but everything above that is a blind faith. I believe that 2019 will not bring any drastic and epic reverse and sudden sky rocketing, it will bring some stability and the growth of price of a couple of thousand dollars. Keep your hope, but keep it to the minimum.
