The SBD price has gone over 1 USD, and is currently trading at 1.093 USD, while STEEM is also down at 1.092 USD, making it cheaper the SBD.
With the SBD price being pegged to the US Dollar, you can expect some intervention by the witness nodes, or the market in general to bring that price back down to parity with the Us Dollar.

The Steemit Market still has STEEM slightly more then 1 SBD, at 1.055SBD per STEEM.
This is about as cheap as i have seen STEEM on the Steemit market for a long while. I have been spending almost all of my SBD on buying STEEM lately as the price has been falling.
With SBD over 1 USD, unless STEEM continues to fall, this gap should start widening soon and You SBD won't get you as much STEEM.
I may be wrong, and STEEM continues to fall below 1 USD, but then the SALE* will well and truly be on, and you'll have to get in quickly to grab a bargain before it goes up again.
These are just my views, and are not to be interpreted as advice of any kind. Always do your own research and make your own decisions on what action you want to take. Don't spend more than you can afford to lose!
