I've checked last 4 weeks. There were 14-20 people competing. In the first weeks of 2018 there were up to 30 competitors. I dont think it equals to: more and more people keep competing.
And , Yes I know that Kilominx has not been out for to long, so it is really hard to see how popular it is becoming, but there is decent amount of cubers doing Kilominx, and that was my main point that I was trying to get across.
Sorry for the confusion, and once again thanks for correcting me in my minor error.
