I am usually on Steemit, because I prefer the Feed it has, DTube only shows me the last 4 videos from my feed on the starting page.
Since I've heard of the 25% before a few times, I only partially read the written post about this topic.

However I wanted to look up if I could find if DTube mentions these 25% somewhere, while I could not find anything about this, I did find the following in the FAQ: "The minimum possible reward is actually $0.02. If your video has less than that, then no payment will be triggered by the blockchain." So that is also a mechanic that exists.
