I heard one reason of the high SBD is due to a Korean exchange called Upbit, its connected to their biggest messaging app called Kakao which allows them to by SBD directly using fiat currency without any need to go through Bitcoin.
I think you are right that Steem will increase in price soon. It makes sense to hold on to Steem or buy more steem power when SBD is worth so much
Do you have any links for that statement? It's interesting if it's true!
Here is a link, it's a post from @acidyo
