As a miner I can tell you that hashrate has nothing to do with price, price is the one dictating the hashrate, higher prices higher revenues higher hashrate as miners buy more gear to make more profits, if hashrate would do anything to the price then it would be pretty simple, we all would just buy gear and the price would go up, well, not that simple!
Actually when I talked about the relation between the hash rate and the price of Bitcoin I wanted to transmit there are some cases in which a high or low hash rate can also influence the price, due to the security of a decentralized network being a driving factor to the price of it... For example, of the hash rate of the Bitcoin main network started to go down and down, that would be translated in a deficiency of security against attacks to it, is that correct? So some traders would feel prompted to exit their positions in exchanges to deter risks of the coins losing value.
It is very unlikely that ever will happen to Bitcoin, because the strength of this community, but it is the case in small coins, I am sure it happened to Ethereum classic a couple of years ago when nobody was taking the hassle to mine it and miner went for Ethereum instead.
Anyways, Thanks for your insight as a miner, I am not a miner so I am just giving my own opinion, which could be less informed than yours...
