Hello I see that you mention this coin is two years old but I have never heard of it. I looked back in the history of the Telegram group and something looks fishy. On October 3rd 2018 it was turned into a supergroup, so I cannot see anything before then. But then there were no messages posted between October 3rd and October 25th when the admin made an official welcome message. It seems odd that such an old coin came out of nowhere just within the last month. Now the telegram has 2,700+ members, which 99.9% of them look like fake accounts.

Blockchain and git history can be faked, this strongly reminds me of Bytecoin which claimed to have been much older than it was, see: https://bitcointalk.org/index.php?topic=740112.0

What makes this more suspicious is that the c0ban team runs their own exchange. Does this mean they are just trying to sell two years worth of emission directly to the public?

Smells really fishy to me.
