Maza has a lot going for it, but the focus needs to shift from "mazacoin as currency for many tribes" to "each tribe has its own currency and mazacoin helps those economies develop".
The best model is probably a currency for each tribe, distributed initially only to fluent speakers from those tribes, with a secondary, much smaller distribution, to tribal members who don't speak the language.
There is a lot of politics and profiteering everywhere, including amongst tribes, so nobody should jump on any bandwagon without examining things first.
I can't agree about a currency for each tribe since there are too many small tribes in the USA and each one would need to have a minimum size in the 1000s or 10000s for it to be worthwhile (IMO). But I also see that that would give better ownership and incentives compared to only 1 coin for all tribes. In some ways Maza has the same problem Bitcoin originally had - which was bootstrapping itself with enough people that were willing to spend time and effort on it and invest money in it too. I'm not seeing that coming from American Indians or other indigenous tribes at the moment. If I did, I'd be willing to help them develop the technology
