You're very welcome.
Yep you are so right the RUDEX market is still getting awareness and liquidity.
But you can use the Blocktrades method to get your SBD and STEEM in openledger (which is a gateway to Bitshares). Link here for that post: https://steemit.com/utopian-io/@chiefmappster/how-to-sell-your-sbd-with-bitshares-or-blocktrades-method
I hope it will open up. As a lot of people use the Openledger gateway for STEEM and SBD. I am still waiting on 44 STEEM I sent Openledger two weeks ago.
Hope this helps
It does, cheers
