Yea, but how do you airdrop electronic devices to utilize crypto for those that don't have electronic devices? If utilizing crypto and all it's blockchain glory to those who don't have access to computers/smartphones/internet has been answered, I'm all ears. Then cool. But I see that as an infrastructure issue that no one has directly answered.

POS debit cards.

But in most unbanked areas like rural African villages or Brazilian favelas people have smartphones. That’s one thing almost all of them have.
