I take it back. I remembered Zenithcoin was extremely hated and by and large had a bad rep, so much so that nobody was even interested in the giveaways. The coin dev, Solarcx, was getting 50% of the mined ZTC which was a major sticking point (not to mention his extremely arrogant attitude). He had in the middle also tried using the coins as tokens for some BTC mining which didn't work out.
https://bitcointalk.org/index.php?topic=219644.0So I looked up in BTCtalk again and it seems that the coin was recently sold to 'FrictionlessCoin' which is probably Ed (or Ed hired FrictionlessCoin), who has a very bad standing in the community, and personally to me seemed like someone who has been trying to scam (he has been quite busy, including some fork of NXT and has raised quite a lot of money).
Since I don't have much idea about the business, and how hard it is to try to get somebody like Ed, I would strongly urge others to look into it. But I should add that if I was not invested in I3 earlier, I would have certainly steered cleared of I3 if I heard it was allying with ZTC/FC. Granted, the loss of my puny investments wouldn't have registered; but I am willing to bet lots of others would have the same feeling.
