What I really think would help the people the coin was made for (and give it more point to hold then just speculation for me) would be if some Lakota trades people would set up online shops to sell some of their work for MZC. Then wealth is actually flowing into their community, instead of just kinda spreading around mzc in a way that might actually decrease its value as everyone sells it off with nothing else to use it for.
Certainly that applies to all coins in a theoretical way.
In pactical terms, altcoins need some "hook" to become mainstream. All the phony "buy x with altcoins" do nothing since they offer nothing really. But Mazacoin potentially offers a real "hook" for altcoins.
Natives have an authentic reason for wanting their own currency and a lot of other people in other places understand. If Lakota sellers of art and other stuff offered discounts for paying with Native currency it would get publicity, and if the Native currency they accepted was an altcoin it would be a mainstream practical use that would be supported by others.
The big question right now is which currency Natives will use. Maza will always have some relevancy because it was the first specifically Native altcoin. But other tribes might create their own coins or whatever.
American Natives are leading.
