I have never thought of that!
Why has nobody brought this up before?!?
It has but when anyone has brought it up, they were decried by the community for the most part. We are at a point were mining is almost unprofitable on whole to maintain this level of security and difficulty.
But why? It should be brought up at least twice a week so that people will finally listen! Maybe once a day for emphasis.
When people realize that the cost of mining is the exact same as the price per 3600 per day, no matter what the price and no matter what the real hardware and electricity costs are, it will blow their minds!
When the price was $1,000 per bitcoin, the hardware and electricity costs to run Bitcoin were $3.6 million!
And now, at a lower price, the cost of hardware and electricity is over $600k.
That is like buying a computer for $1000, but if the price of corn goes up, your computer suddenly costs $2000 more. Even after you paid for it. And your electricity price jumps too.
