You are correct to use the term "investors" with quotes, but if I understand your intention, you are suggesting they are gamblers, and therefore deserve to lose.
You're talking about the general public who for the most part don't own stocks, or when they do, that is treated like gambling (RobinHood).
Then you get big name stars, people they trust, to tell them they should be buying crypto. They see it go up, and then see they don't have to spend more, they can just get more, like BNPL, or payday loan for investments that go up. They say "yes please, how much can I get".
Sure, some people were just a*holes over leveraging themselves and taking a risk. But I suspect many people didn't know how deep they could go, or what they could get themselves into.
Even if you disagree with how somebody got into a situation, doesn't mean you can't have empathy for their position.
