So you need to be aware of the risks, and aware of the potential profit at the same time, if you can do that then you would be able to actually make a profit from it as well, should be considered a good idea. I personally know the risks and I also end up dealing with whatever it can provide me as well, and that is why I invest what I can afford to lose. If I end up losing it all, I won't be poor, if I make profit, I will be happy. Those are the options for me.
However, I do know that I am going to work towards getting richer, so having a goal is important, I know that I would retire if I ever have 100k+ in my bank account because that's enough where I live, and that would be good enough to live until I die without ever needing a single dollar more, not even interest. But in order to reach the top of the tree, aim for the stars, if you fail, you will fall back on the tree.
