Yesterday I submited listing form at Stex.com exchange. It's smaller exchange with 24h volume of $2,339,448 (654.67 BTC). But they offer some FIAT trading pairs too (EUR, USD, JYP, RUB), so it would be good for Steem to see STEEM listed.
And here is their response...
As you can see, they are unable to list STEEM, because they do not support such coin platform.
This is the reason why I'm working on EtherSteem.com.
