This project is a dead Korean project. Of course, the CDC token is still active in coinmarketcap and coingecko (ie the page does not say inactive)
The CDC's rating on coinmarketcap is currently 2673, which is a very bad rating. According to the market pairs section in CMC, only one active pair in an exchange can trade this currency, which means that if this pair is removed by that exchange, the tokens will be completely worthless. I suggest you do not buy this currency even for a short time because I personally had the experience of devaluing a token that had no project behind it and about $ 100 of the money I had bought the tokens was lost.
