This is a fiat Trading platform from Korea called Bitfriends. You, all should have been aware of how Korean Exchange operate, nevertheless, since this Exchange support fiat currency, KRW is the only fiat supported. This Exchange started business since 2018, and now has it list to be untracked in coinmarketcap. I think this exchange taught they will be able to continue good the way they started, thereby giving them the gods to name their Exchange the best Exchange across the globe. This can't be possible, besides it only support KRW as the only fiat currency supported leaving others aside. The customer support team is very bad please don't bother to message them either via telegram or Gmail. The exchange is not functioning any longer. I strongly advise the previous users of this exchange to keep hoping for the arrival of the exchange from maintenance.
