People will always enter the market (to produce) if there is a difference between the price of a Bitcoin and the cost to produce a Bitcoin (electricity, equipment etc).

If the price goes down and it costs more electricity to produce a Bitcoin that is economically viable, people will leave because the juice isn’t worth the squeeze.

So the same relationship works inversed too - difficulty to mine and electricity consumption is related to market cap / price from an econ perspective. I agree with your point on Bitcoin hype, but the production side is just economics and people trying to make a buck if there is money on the table.
