No need to change it. Soon SBD gets back to ~$1. We've seen how a couple months ago SBD was trading at premium and then stabilized after price of Steem is increased and covered the demand for SBD.
The rule is simple. Have some SBD - sell it! The community should keep SBD from rising above $1, protocol keeps it from falling below $1.
