This is a Chinese exchange which was established in 2018 and supports fiat deposit only. Its markets included btc,ETH,usdt,etc. It support erc-20 tokens. I can say certainly that it is a well developed exchange in the sense that the developers have some kind of experience. Registration is quite tough Requiring a long tough KYC process. Trading here is very explicit and interesting. It allows for fiat trading and cryptos trading. Its language translations are inadequate allowing just two languages; Chinese,English. They seem to be low in funds now because they started an air drop which they abruptly ended. They never actually talked about security and never gave guarantee on funds security
