Taking part is the point. Learning is the point. Understanding what has been overlooked is the point.
The only way to learn is to get in. And your investment losses are the cost of learning. The problem is that learning nowadays is getting very expensive. Buying gold only to realize that you can't do much with it, is expensive. Buying bitcoin only to realize that you can't do much with it is also expensive. But it took me those two purchases to actually learn that money is useless. Whether gold, bitcoin, euros, they are all useless until you trade them for something you value.
Thus the first thing is to think not on what to invest, but rather what do you want? Until then is color paper, a number on a database, and a shinny metal. And they all come with imaginary gains and losses measured on another arbitrary scale controlled by the government.
