How do I know mining equipment is actually good and worth the money? Can I even do it at home if I buy the equipment? Honestly, these questions are more theoretical. I can’t even imagine what kind of money this would take.
The investments need to be serious. Without enough money, getting into mining is going to be really tough. I think it was the same back then as it is now. But now there are platforms and services that provide ready-made equipment, and you can immediately check, for example, antminer s21 cost, see how it all works, and plan for hosting in a powerful data center. Don’t try doing it at home, trust me.
