It looks like it has a static price value for BTC, but that skews it because the electric bill is due monthly
No, it's gross mining revenue in USD. Basically (block reward)x(market price)/difficulty at a constant hashrate, using published historical data. Electric bill is not in it. Did your OP involve utility or other costs at all? It looked to me like you were simply lamenting low gross revenue. Please clarify if I misread it.
I fully admit your chart is accurate .
I see a gross revenue chart that is being used in a misleading manner, since you left out the gross costs chart,
but if you want to say that gross revenue has dropped per th okay yeah fine
To not show that cost per th and power per th has decreased enough to fully offset the revenue per th is a joke
Once you do that net revenue shows up.
Frankly gross revenue means nothing to me
Now the fact that net revenue which is what you are leaving out is clearly what matters to me.
Proper way is to show that is gross revenue decreased per th
and show that gross expenses decreased per Th.
So I fully admit your chart is accurateI don't bother most of the time but the accountant in me hate to see gross revenue without gross expense and of course net profit.

That is why I said your chart is a joke. < and that is not what I should have said although I did say I did it as a shock value statement. To get attention
Below is what I could have said:
I stand corrected your perfectly accurate chart on gross revenue was used in a manner that is a joke. Since you left out the charts showing cost and net revenue many people without a background in accounting will be mislead and not realize net profits have not dropped.That is a more accurate description on my part. But it lacks the shock value of my first statement.
Hopefully people read this post and realize what I am talking about.
