Mandala: 1000 USD daily limit, 30000 USD monthly limit
Is Mandala exchange still operational and working fine?
I remember they first started as total clone of Binance exchange and they even used their backend engine, but maybe something changed after Binance introduced more restrictions.
Last time I checked Poloniex and Coinex exchange had $10k daily limit, but this numbers are changing all the time.
Yes, originally their exchange ran on Binance Cloud, using Binance's liquidity pool.
After Binance sjut down their cloud exchange program, Mandala pivoted to independant exchange. If you had an account on the old Mandala exchange, it wouldn't work with the new one. You need to create an account again on the new Mandala exchange.
