To my knowledge only federally recognized tribes receive funding from the federal government. It's obvious that the money (dollars) isn't helping those populations (corruption?). The way I see it, Native American reservations are micro-nations which claim to be sovereign nation states. I know for the Navajo Nation, if they (Navajo Gov) do not comply with the feds rules, they (federal gov) suspends funding. I'm not sure if it's the same for other Native Nations. It would seem that like Native American Nations (specifically Navajo Nation) are subjected to the federal gov's will and are controlled with an economic leash. Until that leash is severed or somehow the funding is linked to MZC, then I can't see crypto being used on Native Nations. Those populations need to know there is value behind the coin and is backed by Mathematics and isn't controlled by humans (whom are corruptible).
I think Native American Nations (micro-nations) are a good test bed for blockchain based governance imo (Bitnation/Etherum etc). Either way, I think it's a good idea for Native American living in poverty, to use something other than federal government's dollar. I think the deeper problem is that Native Americans Nations are not (at least technically) sovereign nation-states. More like a quasi-sovereign under strict supervision from the US Government.
The goal is to help American Natives ignore the U.S. government without consequences, not have some better relationship with it.
Today American Natives are unified by their powerlessness. No matter where you go in the United States Natives are going to be slightly excluded from the power structure. The goal of the United States has always been to force Natives to convert to European culture or die. A lot have tried to convert, to survive, but on the whole they are still not assimilated. They are also unified by their lack of a proper economy and as far as I know by their lack of visible leadership amongst themselves.
Hundreds of years ago they were like 'micronations', but today more unified.
The question of 'governance' should not be tied to economic factors like currencies etc.
Economic issues are one thing, cryptos are a potential stepping stone to some more traditional economy. Governance another.
The connection between economics and governance is what has allowed the Natives in so many places to be so thoroughly fucked for so long.
If a person has commodities (food etc) or derivatives (currencies etc), it should not mean they are now in a position to be fucked by whoever controls the currency.
