I wish we could see africa rising and evolving out of what is certainly a shithole currently, specially in places like Ghana. A global currency would bring them into the global economy, but it must be affordable for them to use it. On-chain transactions in Bitcoin are too expensive for poor people, but thanks to Lightning Network, they will be able to participate.
I think we don't need further blockchains or tokens, just BTC with LN will be able to make BTC usable for poor people too. They will be able to sell their scrapyard resources all over the world for better deals, they just need someone smart to set it up in there for them and there is always someone smart that will find about it, even if living in a hellhole like Ghana (go watch Ghana scrapyard documentaries in Youtube).
