In a rising market, the price of Bitcoin is not greatly affected by mining difficulty because those who mine take into account market variables and can bear the loss for several months, but in a falling market it can be a good indicator of the approaching bottom or determine whether the price will decline further or will stabilize.
There is no such thing!
If miners could enforce a bottom price we would simply buy twice as much gear and drive the cost for one BTC to 5 trillion!
In reality, it doesn't work like that, the price goes lower, miners quit, and the same amount of Bitcoin is produced, this is not oil when if the price goes too low there is less oil on the market and that produces a price growth, there is no actual demand that needs to be satisfied and that can't be satisfied with 1/10 of the mining hashrate!
That's a pretty cool observation! True, the flexibility provided by the capability to alter network fees to be able to cater for the needs of miners is a brilliant aspect that underscores the community’s willingness to ensure the network remains secure and stable.
Except it doesn't exist, again!
You can't enforce fees in the blockchain, people will simply quit using it if miners don't mine transactions under let's say 50sat/vb. Besides you would need total control over all mining which means
centralization!
Nothing brilliant at all in it, more like a disaster waiting to happen!
