The answer is really not simple, I feel your pain.
Like @vimukthi explain in the comments above. There is not a lot of SBD coins in circulation and a small influx into the Steemit ecosystem can lead to a considerable increase in the value of SBD and also have good potential for profit.
It is however a decision you have to make because you are gambling on the possibility of the Steemit platform drawing more attention (increasing the demand for SBD) whilst your SBDs are devaluing at a very high rate.
