I want to see receipts for can't miss investment mainstream promotion that differs from the gambling promotion you are claiming exists here. Because AFAIK both sports betting and Crypto advertisements literally follow the exact same regulations. There are no exceptions one follows that the other doesn't.
Versus
Mainstream advertisement for both of them follow the exact same path and regulation as far as I know so Im comparing them because it fits. And I have seen exactly zero mainstream ads that proclaim that investing in crypto is a sure thing. In fact I don't believe any of them exists because it would be illegal to do so. This all reeks of a strawman you are just making up and hoping no one calls you on so that you can try and justify such a weak argument. Feel free to prove me wrong.
When I say mainstream, I'm referring mostly to so-called "crypto experts" on social media and finance networks telling novice investors that crypto is guaranteed to appreciate in the future. You hear these guys constantly saying "Bitcoin will be $100K or $1M by 20xx". You don't hear gambling sites promoting this type of can't-miss collective prosperity. But no worries, time will tell very soon. Just please, keep the same energy and don't disappear.
