Any form of proof of work mining that requires me to trust a 3rd parties to do the job is unintresting to me.
If i had to mine Bitcoin. I'd start with exploring the Solar PV Battery space and find a setup that generates 0 cost electricity to run my miners and then scale up (if ever).
Bitcoin mining don't make sense if it's not done by 1 million folks in 1 million places in a decentralized manner.
Bitcoin mining still hurts the planet so long as it runs on cheap fossil fuel.
