I would invite people to visit
https://masternodes.online/ and review other coins as well. You can see many starting ROI are around the 2700% ROI that we have calculated to be practical at 100 masternodes online.
Very well, it is settled that there are many projects has high percentage of returns too, just like yours, I don't think I want to bother poking around them as I am currently busy with seeing how far and serious your project is. I think we need to get back to the main concern here, that you still need to prove your legitimacy. The promised return of investment was merely a trigger that causes questions upon your credibility. The main concern here that I tried to erect as well as solve is how you refuse to inform us your team member, or anyone with clear reputation that can vouch you by stating you're legal, (and by that, also willing to be hold responsible in case of the entire team leave with raised funds). Essentially, this responsibility fell to the team member, which usually can be tracked how real they are in person from their history on LindkedIn and other social medias. But as you refuse to disclose the info, I ultimately offered you to prove your legitimacy to the public by other means, namely asking any of the entities that you've helped in the past to give some testimony. Entities with projects or clear and solid background, not newbies that's credibility is questionable. And so far, you're still not providing it. I, as well as other members of the community here that perhaps also following this issue, am still waiting.
Now, as you pointed out the site, I'd like to point out to public here too what the site suggest on the bottom of their own site,
ROI changes often and is not the most important factor. Please consider Dev Team - Community - PURPOSE/Platform - Liquidity - Wallet when making masternode purchases.
As I highlighted, the site themselves stressed on how important it is to know the team's background.
