We have just words of the dev. It was airdropped fully, exclude premine. And there is no any activity or promotion yet. I cant say really, but looks like dev caught the name firstly and then decided to get profit announcing that the coin can be an official coin of the Olympic Games 2020. But i havent reed any information about using cryptocurrencies in OG 2020.
I doubt it, and after reading your thread, I have a feeling that this one might be a real scam.
I will spend my time to search with Google to find out more about this one.
Thanks for your hints on TokyoCoin and its vague potential relations to OG 2020.
