My hatred of get-rich-quick schemes has nothing to do with class signaling. I hate such schemes because they're almost universally scams designed to siphon money from poor people to someone who already has money. I hate them because I see friends and family spending their entire lives throwing away everything chasing get-rich-quick.
So, yes, that crypto has become a focal point for get-rich-quick is a huge red flag to me, but it's unfair of you to summarily dismiss that concern as snobbish.
