Something is wrong with your Steem supply number, coin market cap says there are 307,712,749 STEEM Right now. Turns out inflation is not really 8-9% because people are converting SBD to Steem, thus creating more Steem inflation. Conversion created 12million extra Steem if I'm not mistaken. To fix this problem SBD needs to go, what can guarantee us that SBD will not fall even more in the future, the 1$peg is clearly just a dream.
