I believe this is another step forward for Bankera. South Korea is full of crypto enthousiasts and Hanbitco seems to be very secure because they passed the self-regulatory inspections of the Korea Blockchain Associatoin.
A note of CoinMarketCap ("learn more about why circulating supply might be missing" at the question mark under Ciruculating Supply):
Note: Circulating supply may not be calculated for cryptocurrencies listed on less than 3 exchanges due to the outsized influence of these volumes on the cryptocurrency price and market cap.
That is a very nice rule. I wonder how binance did register bnb with only one their own exchange as listing place...
