Are those numbers for the bias literally a multiplier in that percentage? Or is it an independent setting that affects some other math on how many are produced? New to the game so don't want to vote before knowing anything else about any of the witnesses, but this certainly wasn't something I was even aware of.
I think I get what you're saying about what they're saying, but if the majority of the newly minted stuff is included in the calculation for the marketcap, but the owners aren't all interested in selling, it might not so much decrease the value of them as increase the demand from the outside-of-steemit economy out in the exchanges. My reasoning being that considering so many people are marketcap chasers, more SBD being printed might just pump the price considering so many are holding for speculative reasons, and as you say do not use them as currency.
Honestly, I don't know how the formula works and maybe one of the witnesses I mentioned will stop by to explain it. I do trust these witnesses to get the calculations right and adapt as required.
