I want to draw your attention to the fact that BestChange did not give any statements that the project is fraud, they only encourage people to be vigilant about the information received.
Yes maybe your right, but claiming a partnership with them on your site is not a good start.
I know you say you just redirect users to their platform but you must not explicitly mentioned partner on your website cause its a big NO if some project found out that you are linkinh the project with them. If they did not noticed or check out here you could get a direct boost on bestchange popularity. I doubt if you could gain any investors without defending your case or proving on the accusation thread mentioned by Juler12.
