Many days ago they banned me from the telegram chat just for asking a simple question why users should use their private key. It did not seem a safe method in my opinion. It was clear this project was scam ..and we advice many people here on bitcointalk and on telegram about it.
Not only you they also banned me and other many users claiming they also got banned for asking those kinda questions like ETCV wallet safety and about the project road map and when ETCV will go to touch exchange but telegram admin behaviour was rude because there have no right answer to respond because project was clear SCAM.
I saw how the telegram admins responded to all people who asking about their wallet and if its safe to input our private key. But all of them got banned for Posting a warning not to used it, its a clear scam behavior. Too bad, still some people lose money on this scam by sending ETH during their promo sale.
