The price of things always change from one price to another price, it come to my knowledge that price of bitcoin changes at any given time, so what I you to understand is that, you are right from what you said so far, because I believe that theirs no time you buy bitcoin that's not the right time, because price of Bitcoin increases and also decreases, so what I know is that if you are waiting for the price of bitcoin to drop before you buy, the person is wasting time, it can never drop, because I know very well that price can't fall back to the price of bitcoin in 2019
