I tried everything including convincing my friend to try a shorter GPU processor instead of those large ones appropriate for mining. The whole point was to see if block rewards make electricity costs worth it, not if electricity costs are not worth it

This question should be genuinely asked once per halving by the bitcoin community as a whole for merit

Edit: the tongue out smiley face, Now there are two.
Interesting idea.
But large mines crushed profit per Watt.
They also see that the coins ran out too fast.
After calling
6 year halving would have meant higher difficulty.
And slower block times. Every 15 minutes not every 10
Ie
2012 1/2ing would have come in 2014
2016 1/2ing would have come in 2020
2020 1/2ing would come in April 2026.
We would be at 12.5 coins a block right now and changing to 6.25
As structured a block price of 3x62k is 186-190k which is not worth mining. We would need a coin price of 150k a block price of 450k-465k for ming to be worth it.
And when the next 1/2ing comes coins need to be 300k so mining is in deep trouble with current coin price.
