The early days of crypto mostly wouldn't even appeal to teenagers, it would have been people with a strong background in cryptography or computing. I would think Vitalik will be one of few exceptions of early adopters who are not in middle age by now. The interesting thing for me with that. Most of the early adopters are aging each year and with the growth of bitcoin the temptation to spend must grow each year. Soon you'll have to assume that if their BTC goes unspent it will transcend their own lives.
