Any project from someone like you shouldn't be trusted, you are tagged for running Ponzi schemes on this forum, not once, not even twice, any project coming from you is foul, sorry I will pass by

TL;DR.
I thought that there's really a description and types of these roi coins. But looking at the feedback trust you have, it's your project that you are shilling and it's a scam per se. I think that it's a style that you have come up to make people believe that you are running a type of 'roi coin' but in reality that it's the name of the coin which is a scam.

ROI? 
Nice name.
But obviously, this was made for a good reason.
You will think you will get ROI but I doubt that.
Maybe they should rename it with Profit coin. That way investors will say there will be profit at the end of the tunnel.

There was a old ROI coin years back, I'm not sure this is it and the old ROI coin is dead I guess, judging with your trust rating it's red flag giving this a chance, no one will patronize you on this one mate, you are involved in creating pyramid scheme projects to scam people
