There are some efforts underway to bring ETH-like smart contracts to BTC, which - if they succeed - will allow all the ETH-powered paraphernalia to happen on top of BTC. But the going is slow. Other than that, there already are some "NFT's" embedded in the Bitcoin blockchain. To give you an example of what I mean, consider the Genesis block, which, while its reward can't be spent still has a private key attached to it. I'm willing to bet that the day the person who owns that key (Satoshi, assuming he's still alive) decides to put it up for auction, the bids won't be zero :)
