Not really I read it and it is the same old argument, saying that bitcoin does not have value at all, but maybe we are all imagining the huge amount of money invested by the miners to mine bitcoin and the technology behind bitcoin which solved several problems that until that point were not solved, the volatility comes from mainly two factors the uneven demand for bitcoin and its limited supply.
I agree. I have read it and it is not what I was expecting to read.
To answer, bitcoin is volatile because of the law of demand and supply. Nothing to add more. Besides, bitcoin wont be that interesting if it is not volatile. It will only be compared to a land that is being invested by some.
