Steemit currencies are SO confusing. We already did this transaction, thinking the SBD would convert at prevailing market rates. Why they made everything so confusing, we'll never understand.
SBDs themselves are pretty ridiculous concept, like a child's conception of how to rig the system. No one is going to fall for it, thanks to posts like yours. So why bother? It really doesn't seem like Steemit creators care about anything other than making fast nonsensical money for themselves, or they'd fix the myriad of problems on steemit. People getting paid a few bucks for writing "hi" in a comment is absurd. Google creators CONSTANTLY reworked their algos to fix "gaming of the system" to create a good product, so right there we can see how the "wild wild west" atomosphere of crypto is actually NOT ideal for startups.
