It is quite clear. What advantage do the viewers get buying the coin?
You better read a whitepaper. There you can find a scheme - users need these coins for subscription fees. If you like, I think you can just change the coins for any other crypto. If not, then you will get some free coins to pay this
Advertisers need coins to play ads. Users can simply buy coins during the crowdsale to have more than they would get through just watching TV. While users pass on tokens to organic content providers, they always receive more from advertisers. So users can come to the platform without having participated in the crowdsale.
will it be also possible not to play ads for some cost? for the fee that would be equivalently to reward for watching ads. if an advertiser want to pay $1, while a user want to get $1. But if he refused, he would not get $1, while an advertiser would not pay any. Fair!
Support your view. Ad-free is an ordinary thing that is provided by almost any platform. Here we have an ability to refuse ads without any payments in fact.
While currently not planned, there is always the possibility to add an ad-free option, if you are willing to reward the content creators out of your pocket through tokens.
