Am looking into mining Bitcoin.

https://www.bitcoinmining.com/getting-started/ is a bit outdated, only useful for a general idea.

https://www.forbes.com/sites/digital-assets/article/how-to-mine-bitcoin/ is targetted more a beginners (which I am at mining, but not at theory).

Don't see the point if cloud mining. The Antminer S21 Hyd looks like a good option.

Would very much appreciate any tips/ideas.
