Google took me to BeyondMLM. I've never been there before searching for OneCoin information. Ignore that site if it's unreliable. Wikipedia unreliable in your mind? And Coindesk? There are no shortage of sites where you can find credible criticism.
If you want to believe that OneCoin are any kind of "business" then good luck to you. Open your eyes, and see how their principal people behave on stage and how little substance there is in their words.
