I have a question for all of you, well those who know.

I have a question for all of you, well those who know. I have not yet made any transactions in the community, I mean, I have not bought STEEM, nor Steem Power, I have only generated SBD and there are them. I have seen other users use the SBD to buy STEEM and then convert them into Steem Power. Can someone advise me what to do?

Thankful in advance.
