I have only used it once and everything went smoothly during that period. However, a time came that I abandoned the exchange because I was unable to trade my USDT for fiat because the bank that I needed the money sent to wasn't available. However, you can only receive payments to a bank that isn't a fintech one. Their exchange rate is good. The exchange has only tron network for USDT then, I don't know if they have added other options. Their bitcoin address is SegWit bc1
I have not use the exchange, although there was a time I opened a yellow card account during the time binance short down there naira conversion but when I opened it everything wasn't looking too nice for me considering the experience I had on other exchanges, so when I learned about other exchange I just decided to leave it, except I just decided to continue using the account if not I don't see any need to but is a good information to the users so that those who have not gotten there app yet to do that within the stated period since they did not state how long it will be unreachable.
