Don't stress your self too much on them. That is already their problem if they lose. Learning is supposed to be free but they choose to pay the price for their wrong actions. Those who learn can still lose but not that often and their losses will only be minimal.
Never hear a news that investing in Bitcoin can make you rich quick but I only see a huge profit on those kind of posts. That still enticed the viewer to follow the same thing. Investing takes time. If someone wants to make a quick money, trading is more suited to this or even gambling. The risk on them are only elevated but gambling can be a perfect fit for those people who skip the learning part.
The higher the risk, the lower the chances, I have never known a single person who could boast that he got rich thanks to gambling. I mean a real person with whom I would know, and stories from the Internet, which I cannot verify, I do not take into account. I think that the surest way to get rich is a business, even a few small diverse businesses will give you a good chance of achieving financial freedom with proper handling of money.
