If you look in my wallet you will see that I now keep it liquid and I'm accumulating a lot of liquid steem when compared to what I have powered up. I find that with the amount of engagement on steem currently, having any amount over 1000sp is the sweet sport for me to earn. (especially because I'm on the @backscratcher trail) . Unless I find something that I really want to delegate too, I will keep as much as I can liquid.
