Great!
It seems that more and more exchanges switched their plans to add more coins with fiat trading pairs.
recently, Dogecoin, another old altcoin, got listed with fiat trading pair on Poloniex.
More things to come for Stellar, with the newest trading pair, daily volume will raise.
Maybe it's much stable and fiat trading is another fee which means more profit on their side. I can see that XLM will gained more volume since it can be exchanged easily with fiat and other cryptocurrencies.
