Mandala exchange is a good exchange. That I don't even know the exact date of establishment. But I guess the exchange was into existence since 2018. I am not happy with what I saw on the telegram of this exchange, though it has many members, but seems inactive for more than a year. The in activeness of the telegram has painted a bad image in the exchange seriously. The exchange in the other hand is highly liquid and has over 10 fiat currencies supported. The trading environment is very neat and okay. The trading fee is also very affordable. The exchange is very safe. Trading here is of no form of hitch. Thanks
