What are you talking about? Everyone should think with his own head. And then suicides and deaths. If a person does not have enough brains to figure out what cryptocurrency is and how dangerous it is, then there is nothing surprising that he will lose money on it. Ie then his problem and his fault, and not those who created or supports the cryptocurrency.
I doubt that there are many people who die because of their bitcoin investment, that doesn't really sound like a big demographic, and compared to wall street deaths where people lose a ton of money, I doubt that would be a big deal here in crypto.
First of all as long as you get in with the amount of money you can afford to lose, you are not going to have any problem, because since it is money you can afford to lose, the worst thing that could happen would be losing that money and that's it, secondly if you end up even losing for a while, in crypto world there is no forever, it will not profit forever, it will not lose forever, so if you end up going down after a while, just wait it out and you are going to reach back to profits once again. Let me put it this way, people who invested at 2017 peak and waited until today, made over 60% profit today, that's right, for each 20k you put in, you got back 35k, and that is actually quite a good return and that is after 3 years of worse market.
