I just have to ask this again

Because I have noticed that the same events repeat themselves, and yet I have to live through them again and again and again. I have asked this many times before, and then the answer is usually "it's great, I've experienced no problems, but what's the point?". I still don't get what could be the point of buying and selling forex or buying and selling bitcoin. To me, this is a risky and strange way to make money. But I've been asking this question for years and years and nobody has ever given me an answer or a different perspective. I'm not saying that this is wrong, but I just don't see the point in this.
