The Russian YouTuber "Ntin Ang" created his own cryptocurrency token called "BITUMcoin". With only 100.000 coins available. Each coin equals a second of advertising on his channel and it is the only payment method for advertising.
He claims to be the first YouTuber with this concept (I guess it is true, because I could not find a similar concept on YouTube).
He used the Waves Platform to create this token.
You can find more information about BITUMcoin on WavesDesk Explorer.

Maybe this will become a new way to pay for advertising on YouTube channels some day?
