I have also seen people calling on $30 SBD's... It is a really hard one for me to predict, because I have strong bullish and bearish arguements.. On one hand I think that SBD's have very little underlying value, and so they should not be given such high premiums... On the other hand, they are trading on a technical basis and are treated almost like an Altcoin now. They are also the leading factor behind Steemit profitability, so whales may buy up the price as an investment in the steemit platform. With higher SBD's price, they make more money per post and make back their investment that way. So we could very well see $30 sbd or $1 sbd... I personally cannot say.. But what I do know is that SBD's are trading on a technical basis right now, so I can trade them short term! :) thanks for the question though!
