There are many programs where it is necessary to watch video to get reward but I do not know about such programs on blockhain and payment in tokens.
Do you mean games where gamers can watch promos to get in-game currency? The main problem for this project that I see is to make their token interesting for people. Otherwise, they won't use this program at all.
I agree, with many of the platforms, having a case for strong utility case is difficult - for us, we have engineered such that the token functionality will be built in.
We have also been forward planning various features of the product that we will release in later stages that make a strong case for the token on our platform.
