I don't imagine teenagers have +1 BTC to be honest, where would they get them from?
Asking their parents to withdraw part of their savings?
Okay, they might have been able to buy some through a holiday job or whatever, but they're teenagers.
They probably spend most of that money on other stuff, like a car (in the US) or on a holiday with their friends perhaps.
Hopefully those teenagers knows how to value money and knows how to use well bitcoin. I know someone who owns some of cryptocurrency and at the very young age, he knows how to deal with life well. They spend their cryptos to support for their studies and of course to buy good things.
We should start educating those teenagers so they will not spend the money in useless things, if you will gift cryptocurrency to your child or to anyone dont forget to teach them how to use it, so at the end of the day they will still have that money.
