If you say it's too late to buy bitcoin now, then wait for tomorrow when you expect the price to go down, which it won't, then you will have to wait for another tomorrow until you can only afford to buy your regret rather than Bitcoin. Those who consider bitcoin to be too expensive or too late to acquire it could have also not acquired it even if they met it when the price was at its lowest.
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
