You need to do lots of casts throughout the day and gather as many reactions as possible.
They're equivalent to the time you ultimately spend on Farcaster, which is your contribution to its future capitalization.
Details in the comments.
1. The key metric for tips allowance is the median reactions on Dune, although a better name would be “daily reactions”.
2. Let's take an example. My reactions per cast are 51. Median reactions 57. Degen tips ~ 30k.
For @runn33rr, it's 9 and 191 respectively. Tips ~ 53k. There are also less significant details like the age of the account.
3. The main thing you need to remember when you come to Farcaster is that you are a mini-factory producing photo/text/video content. The factory must not stop, and you'll only get paid if you produce a lot and your content generates reactions and attention.
