Rob, someone is trying to get me an old, retired guy to learn about investing in Bitcoin. I have gone to numerous websites but fail to understand. Bitcoin's value? They say it has a value like the US Dollar has a Value, they also say it's value surpasses that of gold. It has been compared to a commodity. At least if I were to trade in a commodity. I would have a share in a physical good like coal, or barrels of oil. What value does a Bitcoin have? More than that who assigns a dollar value to Bitcoin? I may be interested in trading, but if I do not understand it I may as well be trading Air.
