funny thing is..
for years i have been running charts of the cheapest and most expensive mining costs.. and treated that as a value window.and in 99.99% of chart plots the price sits within the mining cost value window.
Funny thing is that you are using numbers that satisfy your conclusion otherwise as I've told you elsewhere and you ignored it the cheapest electricity cost is $0.002/kwh in other words your minimum is 20 times higher than the actual minimum.
this is because when it costs more to mine, for instance in USA than the price is. hobby miners switch off their asics to then buy. which then makes the price rise with the mining cost.
You are ignoring the size of the market. There aren't enough "hobby miners" that would buy bitcoin in your scenario to have any kind of effect on the price.
