Calfin Global Crypto Exchange also known as CGCX, is one of a kind exchange claims to be regulated. As a centralized exchange, CGCX also allows traders to buy, sell and trade cryptocurrencies without any stress. This can be done via fiat-crypto means or crypto-crypto trading. While the exchange supports fiat currencies, it also requires KYC verification before you can properly trade on the exchange. I didn't try out the KYC, the exchange claimed to be undergoing an upgrade but there hasn't been any news if development from them neither has the telegram group been active. Anyone willing to try out this exchange should only invest what they can lose. Personally, I don't see this exchange coming out of upgrade anytime soon besides, it was featured as an Untracked Listing on CoinMarketCap.
