I very much agree with @aggroed here. The key point that I am taking away is that, unless the market cap for STEEM/SBD increases SIGNIFICANTLY, we have no assurances that, once that conversion is in place, that we will have an SBD that is tracking with the USD. You flood the market with easily converted SBD and you will crash it. I am all for having stable reward currency that can easily be accepted and converted to fiat or used as fiat it'self, but not at the risk of destroying the very system we love. Leave it as is until crypto volatility can be contained or at least minimized by adoption across the economic system. If SBD can be eventually contained to within 2% of the USD, then by all means, convert away. Til then, don't remove the most attractive feature about the platform at the moment. It is my firm belief that the high price of SBD on the open market is the main reason Steemit has attracted so many people.
