I for one disagree heartily. But be that as it may.
The "fix" could just be that you could do the same type of steem-sbd exchange in both directions - meaning, just like you can now directly exchange (on the blockchain) 1 sbd for $1 worth of steem, you'd be able to exchange $1 worth of steem for 1 sbd. Poof, sbd will always be worth about $1. Right?
It seems that the creators somehow did this on purpose. Or else they just forgot? Seems strange.
