To receive tips you need to stake LEO on your wallet, which you can receive from other people tipping you from the posts you make on your blog or comments on other people's posts. Since it appears that you are a new user, I recommend either creating some new articles or interacting heavily across various posts, particularly the popular ones where tips are more likely. Also, as a side note, it takes a week from the time of your post to receive your rewards, and after that, you can no longer receive rewards from that post.

Hope this helps and best of luck with your journey into the LEO community!
