What fees should advertisers pay for a channel with 1m number of viewers a day? What if I would like to watch several videos simultaneously, will I have several rewards?
I believe you are not able to abuse the system in a such way

It would be too easy then. Probably you better have several accounts for this purpose.
I guess we will have to wait for developers response on this question. I also wonder if "multiple instances" going to be possible.
It's not meant to be a farming mechanism, those credits earned from ads, promo videos or trailers are for you to spend on content you will be potentially interested, this is just my reasoning.
Speaking of content, how TV-TWO is planing to fill its offer for movies and other video entertainment?
I assume you wont be making your own productions, at least not at the beginning

(but are you planing to?), will you rent content from other platforms, like Netflix/HBO etc?
TV-TWO can integrate trailers from Netflix and become a channel of discovery for their content. TV-TWO will focus on shorter videos that provide quick entertainment. Travel videos, drone footage. Why do we believe we can win over content creators? While YouTube is optimizing for the shareholder value of Alphabet, TV-TWO is optimizing for utility to users and video producers to maximize the token value. The economics for content creators are inherently superior on our open platform. While video producers will not stop uploading to YouTube from day one, they will tell their audience to go over to TV-TWO, because they earn more on our platform with every single view. This will lead to exclusive partnerships in the medium term.
About the token farming point: We ensures through occasional surveys and on-screen dialogs that users are engaged. You could compare this to Netflix's "Are you still watching".
