is it because of time zones or is it youtube mostly?
Eu heavy viewers, so yea timezones is a thing. But another is that CS pros are busy most of the time, so they dont stream. Otherwise, S1mple gets like 20-30k viewers when he is live. On the other hand, when pro CS matches are live such as ESL, Blast, or a major, it gets a ton of views. CS2 will bring some casual content back, I expect much higher casual viewers then at least in the beginning
