I did not know these things: "The earlier that you vote on a potentially successful and highly rewarded post, the more you will make in curation rewards." and "When you upvote someone’s post - that value is not being withdrawn from your personal account." Thanks for explanations, it's the first post I'm reading about this.
How many posts can I upvote in one day?
Great question... There is no limit to how many posts you can upvote in a day! But you can only upvote ~15 posts per day at full 100% power. (Steemians that have above 500 Steem Power in their wallet will see a scroll bar that allows them to measure exactly how strong they would like their vote to be.)
Thanks for the explanation @sndbox. One more question, please: besides Steemit Chat and Discord, how can we promote our posts?
Right now I believe those two are the best options! Find a chatroom channel in either one and begin a conversation :)
