Converting crypto to fiat is one thing but I'm more interested in earning crypto through mining. Are there any legitimate mining companies or is it better to mine solo?

There are big bitcoin mining companies that operate at scale with warehouses full of equipment. I researched this when I was thinking about getting into mining myself. These companies have advantages like cheap electricity deals and bulk hardware discounts that individual miners can't get. Some companies even let you buy shares or contracts but you need to be careful because many cloud mining services are scams. For someone starting out solo mining is tough because the competition is massive now. You either need serious capital to compete or join a mining pool where you share rewards with others. The big companies make money because they operate efficiently at huge scale. Individual miners struggle unless they have access to very cheap power or free equipment
