Bitcoins have been over a couple of hundred dollars for more than 5 years now. Kids can only get so many by mining. Don't imagine too many teenagers have 10+ bitcoins without family help in getting them.
Bitcoin is maturing, and so are its holders.
Alts are probably a different story
I don't think so,I don't think if they were more committed on crypto when they don't have commitments such as families,or children.I agree that on their 30s or 40s were more consistent on doing cryptocurrency.
