In my opinion, it is still the how much you invest, yes if you invest a massive amount of money at a higher price you know that you can still gain or earn it. Predicting when bitcoin cost will decrease is very difficult because there are some money traders and investors in this world. We know that bitcoin cost is very unstable so if you invest a bigger amount of money in the time that you think that bitcoin’s value is very affordable on that time I’m sure that you will not be pity. It’s not all about when you should invest, because if you can afford to invest on that time, why will you still wait for a long amount if the percentage of it is very meager.
