If you try to say that the price is highly volatile and unpredictable, then you are right. But if you discard all the pumps and dumps that we have seen in the last years and open the all time charts, then you'll spot that the price has been growing constantly. If you stick to Bitcoin as a long term investment, then you don't have to worry about the usual fluctuations as the end result is that you end up seeing your investment value grow year by year. That's the most important thing for long term minded people.
My thoughts exactly. And actually it's not so uncommon for scientisst or any researchers, for example, to discard a couple of big discrepancies from a diagram in order to see the trend. If we apply this method to Bitcoin's all time graph we'll see that the price of it is rising from the beginning. And that's a good thing because yes, the price of bitcoin matters.
