It doesn't matter whether the ICO ratings are good or not. I mean, most of them are actually not reliable. There's been a lot of cases when the project gained a lot of good reviews but in the end the project was not actually realized. Kepler is a well established company so there's nothing to worry about, I reckon.
Building their trust soon is a very major red flag and not a good sign. It's the pattern of most exit scammers to build their trust so soon and so quickly
Building trust from the get-go is a major major red flag for you? 0__0
You know what, I will never ever spend a single cent on a project that is so blurred and so unknown from the get-go.
I must know the Team, know their Advisors, I must know everything. If that is not given on the first day or week forget it, you will not get a single cent from me, it just goes to say that the people behind that project doesn't want to be known and they do not know what there are doing. If it's a legit project you will see their faces, you will know their advisors and you can contact those advisors if they are really into this project. How can you do due diligence when you can't see names and faces on their website or whitepaper?
