That's an interesting observation and I agree with you (I'm a first-wave crypto advocate myself).
I've said this before here on HN, but I think crypto exchanges should require new customers to pass a relatively strict test about crypto, investment and trading basics before they could start operating with cryptocurrencies or other such trading products.
I think crypto exchanges are an ideal platform to do this because they're usually the onboarding ramp for most new crypto users, especially the ones losing massive amounts of money recently.
I believe this would be in the best interest of the whole crypto industry and could be a massive improvement in the reputation and usage of crypto in the long term, even if it could have some detrimental effects in the short run (due to being an entry barrier for new users).
Because it's obvious to anyone not asleep at the wheel that many new crypto users do not know what they're getting into, or rather, all the risks that they are undertaking when they get their money into crypto exchanges, cryptocurrencies and/or crypto-related... thingies.
