I am not familiar with altcoin mining and how the mining difficulty is adjusted when hash rates drops for reasons like you said in your post.
...The price during this time, will usually go up as well, as some miners in warmer areas are forced to buy or hold or FOMO as they watch the price climb and climb.
I do not see how this is related to the price. Why would they buy or fomo when the situation dictates that they should sell their mined coins so they could pay for fixed maintenance cost of their mining machines?
