You can buy SBD on Bittrex and transfer, or you can convert STEEM to SBD via the internal exchange.
Although there is significant volume for SBD and STEEM on Poloniex, don't buy there until they fix the deposit/withdrawal issues they've been having (for a long time now)
I'm ignorant in these matters.
Well, that's what Steemit is for. To learn and help each other out :)
Plus hopefully make a few dollars in the process of course.
True and thanks
