It's not a
proof! website that you send is not Sergey's website and in this video he never said that he didn't create Mavro. Websites you send is used to fishing and scam.
Here is official Sergey's twitter - https://twitter.com/Sergey_Mavrody , where he proofs, that he is Mavro adviser. Thanks for your information, I appreciate your promptness. It is good not to raise any suspicion on the project that those who want to invest can only make the decision on what the project offers itself. It is good to check if it is possible to inform us from several sources before writing here something that can affect negatively.
