I was responding to a comment about what to do if you already have SBD. Converting it now to STEEM on the internal market is a bad idea right now. You'll get 1 STEEM per 1 SBD. Use the external markets and you could get over 5x that of STEEM as of writing. That is what is most beneficial to a noob and to the platform since we want more STEEM powered up and they want more STEEM power.

I would not buy any SBD on the open market right now.

For publishing I would definitely use the 50:50 SBD and STEEM option which will maximize your ability to acquire STEEM through external markets.
