Its players are fully aware of most of it being a casino. They play anyway. They do not want to be "rescued" by your moral preaching or regulation, they willingly take big risks, often lose it all, and then do it again.
Crypto, as they see it, is the only asymmetrical bet of their lifetime. The only way to "make it". And making it doesn't even have to mean millionaire status, it could just mean any type of life improving wealth.
So "adults" preaching about why they can't just be "normal" and financially sane, are deeply out of touch. "Normal" as in...student debt, stagnant wages, unaffordable housing, healthcare costs that can bankrupt you, double digit inflation, one crisis after the other (9/11, financial crisis, COVID, war), job insecurity, climate change, political boiling pot...that kind of "normal"?
Many if not most young people cannot get ahead by doing "normal". They can't even reach middle class. If doing all the right things leads to a miserable result, any escape hatch is embraced.
