i think it has something to do with the price being so low, i saw another person on here saying that if the price goes too low (around .13 like it is now) then they will stop giving out SBD and resort to what they are doing now? not sure on the details.. if you find out let me know too lol but it doesn't bother me for too much right now because if you need $ still u can trade liquid STEEM instead of sbd?
