I perk up when I see Gold smelting videos; is that a sign that I could be happy as a metalsmith?

Where can I get more information on being a Gold smelter? Videos other than just YouTube, and Wikipedia. I watch Yukon Gold, Bearing Sea Gold, and Alaska Gold rush and I think that other than the video crew that the only people who make a profit, (and get to see Gold), are the middle men who buy and/or smelt Gold nuggets into bars.
