I have also some SBD, but it's not wise to convert it to steem, so i just hold my sbd and wait for the price gonna go up little bit, because steem and sbd usually correlated to each other when it comes to prices, i've seen the chart history between sbd and steem and they are pretty much on the same price, sometimes sbd are higher if steem drops its price, and sometimes steem is higher when there's a sudden jump of the price. you see their chart history here>>>> http://steem.supply/@talanhorne
