If a mining farm does go offline, other miners are taking delivery of new hashing units all the time
And as has been mentioned, if the miners all push the rate too high, they have no choice but to stop because the price cannot sustain profitability at too high a difficulty
honestly, you're all apparently afraid of something you've never taken 5 minutes to think about previously
No.
The price will go up if the difficulty increases. Simple supply and demand. It will take more effort to get something it will be worth more.
I am not sure if people are afraid, it's just interesting.
Debatable if hashing power follows the price, or price follows hashing power. Normally, hashing power should follow the price. "Why would the miners add more power if it's not profitable?"
But on bull markets, or the expectation of a bull market, I believe miners speculate, and add more hashing power in anticipation of a better profit.
