Regardless of what a waste as someone may say it is.... I say go for it!
I was told I was nuts for building a USB miner farm and looked how that turned out.
Whatever happened to 1 CPU 1 vote?
It's dead coz with 1 CPU 1 vote, you get 1 100TH/s miner is literally 3333333 votes
And the network is then a total of 8433333333249 votes
So your 1 vote counts for nothing and is unlikely to ever count for anything ever again.
Meanwhile all those people complaining about the power cost to run the BTC network get a beyond ridiculously good argument pointing out that it would take 8433333333249 CPU cores to do the current network with CPU power and that would be more power than available on the planet.
Is there a reason you don't walk everywhere, every time, all over the world like they did more than 5500 years ago?
How long does it take to circle the globe in a plane? About 45 hours? How about to walk? About 3 years if you walk non-stop?
So that's only a tiny factor of about 584 - not an enormous factor of 3333333.
Starting to see the picture?
If you get in a fist fight. do you strand there lightly touching the other guy 10 on the shoulder with your little finger?
Then when he punches you 10 times hard in the face - you lose.
The probability of a CPU ever finding a block is so small that it would be a waste of electricity since it wouldn't help secure the network.
Chances are pointless at that level.
