I started Dreamstime back in October 2019. My portfolio consistss of around 380 images and 380 videos. In total, to date, I have made $18.
Of course, I have Python scripts that manage the uploads to all the stock footage agencies at once, including creating the agency-specific keyword csv files, so it takes me almost no effort to continue uploading to Dreamstime at this point. So, personally, I have no real reason to stop despite how bad the earnings are. But if you don't automate it, I would say no.
