All coins, including MZC, are still controlled entirely by speculators. So far there has been no effective project to develop an alternative economy with any coin, to my knowledge, Though bitcoin is in a pretty good position if something forces people away from fiat in some region of the world.

MZC does have better potential than most coins and it seems to be controlled largely by people in the dev team and private people like Alao, who are interested in establishing an economy independent of fiat and central govs.

There are no major projects going on, as far as I know, but there are Mazacoin speculators willing to donate / invest / subsidize any majority Native projects. If anyone has ideas on how to establish a workable economy, projects that might lead to economic independence for American Natives, they should post those ideas on https://bitcointalk.org/index.php?topic=1193897 or any of the other channels mentioned in various threads.
