I tried once: uploaded a set of small images to two secondary markets that support/not support royalties, to see what "creator economy" really depends on to survive.

The result was quite awkward, the one supporting royalties was even quieter, the one not supporting royalties had faster transactions, but the comment section mostly talked about floors and doubling, no one cared what you drew...
Honestly, everyone talks about creators, but in practice they just click the buttons with the lowest fees.
Recently, I saw someone linking ETF capital flows, US stock risk appetite, and crypto market rises and falls in a rigid interpretation, and I felt even more: narratives come and go quickly, but slow variables like royalties are the most easily sacrificed.
Anyway, I now prefer to treat royalties as "tips," take what I can get, and forget about it if I can't, don't expect it to support the long term.
