Do you know the character or team of the Umbria project? what makes you believe in their vision and mission? I didn't get much information and when I browsed the Umbria website the information was very brief there
there is no team list on umbria website and the site look very simple
also i can't find the whitepaper link too, only found a little informations about this project in the
litepaper from Umbria
Perhaps this is why the developers have not yet started promoting the project, as not everything has been prepared to show it for community and investors.
I think the OP rushed a bit with the release of this information and we should wait for the official ANN thread.
