I know for google but if someone has a useful link I would be grateful to share here that I can read it.
I do this only for the purpose because of people from my ambience they are increasingly asking me about this "coin" and I want to give them a wider picture of what's behind it
LOL. You've made my day.
You may start with https://en.wikipedia.org/wiki/OneCoin
"OneCoin is a Ponzi scheme[1][2] promoted as a cryptocoin with a private blockchain. It is promoted by offshore companies OneCoin Ltd (Dubai) and OneLife Network Ltd (Belize), both led by Bulgarian Ruja Ignatova.[3] OneCoin has been described as a Ponzi scheme, both because of how it has been set up and because of many of the people who are central to OneCoin having previously been involved in other such schemes.[4][5]"
There are many warnings and proofs that Onecoin in a ponzi scam.
