After a long period of SBD being undervalued or fairly valued, as well as undercollateralized, you may have noticed that SBD has now gone back above $1.
This presents stakeholders with the opportunity to vote a portion of rewards to use the overvalued SBD to buy back and burn STEEM, channeling the SBD overvaluation back into helping support (and ideally increasing) the STEEM price.
This is what does, and I will once again begin a series of daily
post and comments which will use their rewards to buy back STEEM. By voting for these posts and comments you can express your opinion (which I share) that supporting the value of STEEM with overvalued SBD is one of the best uses for the reward pool.
Detailed rules for are described in my previous blog posts on the topic and easily accessible as my blog history is pretty small.
