I think NTF has not revealed its potential. By the way, there is a project that is going to monetize Tik-Tok videos, people will be able to sell / buy NTF. The project is called YouClout and they will have an IDO tomorrow.
I heard about it but Im not sure how will that work or be accepted in tiktok community. I dont use it so I dont really know but I guess there will be some legal problems.
I do think that such an idea of monetizing Tik-Tok videos will be successful as it is one more opportunity for bloggers to earn. What comes to legitimacy, Tik-Tok should launch its own token so as to make it easier for people to sell and buy videos. They can even organise NFT-marketplace, it will be a big upgrade for this platform. Now NFTs are already being used in Tweeter I know, but just as avatars of profiles (Burger King and Coca Cola).
