Telegram TOn ( Gram TOken) which raised huge amount in ICO as far i knew they raised 850 million in first round agian in second round also same even after this much fund raise . I don't see any progress . This kind of ICO's really ruining crypto funds . People are loosing belief on Crypto Currency .
AFAIK, they had a private ICO where selected private investors made investment on the token while they haven't come up with public offering as of yet.
As the token is still not implemented on the telegram app and no news about it, it could have been cancelled and the funds returned to the private investors privately. Still we'd be loving social app like Telegram issuing a token through ICO.
