Yesterday you posted a link that got 100 sats, then you posted another that got none. The 100 sat link didn't get more than 1 upvote, so it isn't 'top' content. You other post got no upvotes. 

Similarly your comments were upvoted, but not enough to be 'top'.

You earned many sats yesterday despite not getting rewards. And you didn't get rewards because you didn't end up contributing to the best content.

Did you post or comment something that a lot of people upvoted? Did you upvote something good, helping other people discover it, that a lot of them ended up upvoting too?

Those are the ways you get rewards now.
