yes i agree.. i've been changing my steem dollars to steem power as soon as i build up enough and just keep a small float of dollars for promoting my posts.
Its so disheartening to post a really good post and to see no votes
So yes i would definitely recommend buying steem power
Agreed 100% you only need enough steem/dollars just to do basic promotions and tip people other than that all should be dedicated to Powering Up your SP!
