The number of people you like to follow depends on how much time you like to spend at Steemit. I don't have to much time. So I better limit it to 25-50 people. Cause imagine how much I can read every day is they post 3-4 times a week?
Bots also get curation rewards. They are just like any other user, only programmed with code. You better use them straight away. Cause of the bot upvotes your posts a few minutes after you published it, the bot will get less curation fee.
Btw, why don't you power up the 34 Steem?
