This is a very good question cos I’m also experiencing it too. When I got 100SP, I realized that I could fully upvote .001 with my voting power.

Then I begin to ask myself how can I earn curation rewards with only 100SP. With all my search I found out that if I curate or upvote 7-10 post manually on a daily basis i would be able earn some rewards.

I gave it a try and I saw it works out for me. With the time being stuck with work all the time, I use Steem Autovote to upvote some of my good steemians and also my fellow Plankton, so I can upvote the as soon as they drop a post.

Peace ✌️
