I'm still not seeing how a blockchain or bitcoin plays a fundamental role here? Teens (edit: adults) in subsaharan Africa can own stock, so can most Americans. They don't and I don't think it's for lack of blockchains or digital wallets.
is that true? I thought most states had age requirements for trading securities, usually the age of majority.
Unless you're not trying to say that "most american teens can own stock".
Just pointing out that people under the age of majority are, in fact, restricted from trading securities (for obvious reasons).
I did mean "most Americans", not most teenage Americans. I think OP was probably making a point about access to resources and markets, not age related legislation.
