This is completely untrue.
The way it works is that hashrate and difficulty follow price usually one way and not necessarily the other way around.
When hashrate goes up before price, it doesn’t mean the price has to go up with a certain coin. There are times in the past when this happened but it doesn’t mean it will happen again in the future.
I think it was just a coincidence that there was new ASICS released and Bitcoin just happened to have a massive rally in the next few months like in 2017 and 2020.
Oh I know my post was not implying that it would happen without a doubt just that it is a potential outcome. I dont think we have ever seen such a large shift in hashpower like we will see when PoS is finally implemented. There are a variety of potential outcomes I was just suggesting a possible one. While it may not be tied to price rising there will likely be a large spike in liquidity with miners selling more to pay the bills using certain coins.
I think it's true that the price of the coin will rise with the hashrate. Because as we know the price of first crypto Bitcoin is depended on it's demand. So the more people use the coin for transferring or mining the more price will go up, like we've seen on Ethereum, digibyte and siacoin examples.
