These celebrities and influencers like C. Ronaldo do not cares about their followers than money. Binance will pay him huge amount for endorsing him. He care more about the money he will receive from the endorsement and not the protection of his followers. But people also supposed to make investigation before investing in anything.
NFTs are only hyped, the hype came and went. It was bull run period that Binance endorsed C. Ronaldo. He should be fearful of what can come after bull run which is bear market. NFTs are better just for rich people like Monalisa owned by rich people which is an physical artwork. That is how NFTs should be seen, but everybody wants to have NFT which makes most of them valueless.
