there is a mining:market dynamic paradigm that plays out
people always look for th cheapest ways to get bitcoin. so yes there is a correlation between market:mining during low speculation

firstly it isnt an instant reaction as soon as a block reveals its hashrate the price of mining calculates and markets react.. its a bit slower
EG octobers hashrate curve led to novembers market reaction

secondly its more about a underlying value (below the speculative price) support. so it wont help you much predict the next speculative hype.

however when you see the hashrate move and has a sustained period of a certain level. the markets react.

people will always find the cheapest way to get bitcoin, so that could be mining when hashrate is low in comparison or markets when hashrate is high, but they end up pulling each other up and down to equalibriate themselves in a low speculative time

in short right now based on mining cost. 104*average exa hash rate=bottomline market support

so if market prices are near the result you know its a good price.. if the market price is way up above, then the price is too high and not sustainable and has high chance of coming back down

the magic number 104 is based on the mining cost of the majority at present. using the most efficient costs. so its the bottomline value.

this number can change periodically when different batches come out that are more efficient. but instead of doing the complicated maths i just simplified it down to the easiest representation of the mining cost math so that people can easily calculate costs in one easy calculation.
