Hi @wf9877
If you don't have a lot of Steem available and you have converted it all to Steem Power you can use SBD for bid bots and as far as I am aware that is the best way to spend your SBD. I would however avoid holding on to SBD for to long if the price of the coin is high (US$3 - US$15) because SBD is being printed at a very high rate. This means that if you have SBD in your wallet, it is being devalued at a very high rate and you are losing value.
There is however 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 (if you hold SBD).
It is a decision you have to make because you are gambling on the possibility of the Steemit platform drawing more attention whilst your SBDs are devaluing at a very high rate.
Thanks very much!
