Very good idea and decision that you made. I think the SBD Markets need to be more liquid in the outside world beyond Steem-internal ecosystem. The internal conversion mechanics work like they should...not perfect but there are clear rules that are being enforced. But the price discovery on external exchanges is in the hands of pure speculation, because of a leck of volume, market participants and overall crypto related hurdles.
Therefore I would really like to see an easy to use in build market exchange for fiat currency like USD, EUR and others. If we could achieve a permanent flow of fiat capital into this ecosystem than I suggest we could see SBD more stable and valuable as a good trading pair for fiat currency.
