That's obviously bad. But kids have always bought drugs.
That is an example of how kidos can create their own economies with crypto. Money is something everyone understands. Even penguins & chimps understand trade (for sex, with the link provided)[0].
If there's a way to ensure children didn't have access to drugs of abuse, I'm all for that. Drugs & developing brains !mix. & it seems prohibition hasn't helped any. It's spawned more concentrated substances & resilient drug markets.
I just overheard my kid's friend talking about how you buy everything you want on "the dark web" using bitcoin to pay for it.
