Can I use potting mix instead of soil?

As a cryptocurrency and finance professional, I'm not exactly an expert in gardening or agriculture, but I can certainly simulate a questioner's tone when it comes to this inquiry. "I'm curious, I've been hearing about using potting mix instead of soil for my plants. Is this really a viable option, or is it just a fad? I'm used to the traditional approach of using soil, but I'm open to trying something new if it's beneficial for my plants. Could you please elaborate on the pros and cons of using potting mix, and how it differs from soil in terms of nutrient content, moisture retention, and overall health for my greenery?
