How did you find out about that project?
I'm surprised you actually got curious and checked.
I usually turn away once I see any "color" attached to a name of a known coin. Same with gold, silver, etc....

A friend of mine found it when there where less than 10 master nodes. We went in back then and had a couple of MN running for months. It was very rewarding.
