It's honestly a big guessing game right now. SBD seems to have stabilized out a bit, but is still sitting at about 17% less than 1 USD after being listed for about 10 days give or take. It's priced at about 83 cents right now on Poloniex after doing the math last time I checked.
STEEM on the other hand fell roughly 12.5% in the past 24 hours, but I have a feeling some of that was due to the hard fork a couple days ago. Steemit now makes you wait 7 days before SBD will convert to STEEM after a request to make the conversion.
