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.
The sad truth is, Bitcoin is volatile because it doesn't have real use in the economy as a currency with which people buy things and pay for services. Uneven demand that you talk about is a straightforward consequence of that. If Bitcoin was used as a means of payment, the demand for it would soon stabilize relative to the amount of goods and the volume of services offered for it. But because the vast majority of demand comes from plain speculation, it is prone to wildest fluctuations leading to extreme volatility.
