Not many people want to sit on slowly-rising gold for 20 years. People are often trying to find high-yield, low-risk compromise so they are trading instruments and switching between them instead. The point is that it is very difficult, practically impossible to time the market. So the commenter was right - he got lucky that one time. And if you were trading in the markets for many years, you would see that occasionally you would be lucky too. But unless you employed some kind of risk and money management, the other times where you would be wrong (and those times would definitely happen as well) losses would cancel out all your lucky profits. I was lucky a couple of times too and it means nothing.
