I'm also selling all my SBD that I earn and buy Steem Power. But my decision is simplified by the fact that I'm new and I have really small amount of SP so it's not like I could have anything better to do with the SBD that I earn.
I definitely think Steemit and STEEM will have a great year ahead. It's just that the crypto market as a whole had a pretty rough start of the year like it happens most time. It will pick up the pace tough in my opinion.
