NFTs don’t have traditional paper trails that you can follow to prove ownership of your asset. When you buy a home, for example, legal title passes to you and is filed as a public record.
Although your NFT purchase is logged on the blockchain, your actual asset doesn’t exist there — just an identifier showing you made the purchase.
In fact, in states like California, it can be questionable to say that you actually “own” an NFT, as what you really own is a license to use the NFT. In that sense, NFT ownership is a bit more nebulous than you might be used to with other financial assets.
