Hello @drutter The thing with SBDs is that it is supposed to represent the Steem economy as a mature market, where the price of Steem coins can rise or fall, but in theory, the price of SBD is supposed to remain at $1 US Dollar or very close to that. This would thus eliminate vendors' and buyers' worrying about the Steem price fluctuations when using SBDs since they are supposed to "always" be $1 Dollar.
If SBD can become a true stable coin, this could bode well for the overall value of the STEEM blockchain, and Steem coin. We'll see.
