Getting an NFT is like getting any other asset, just because it is digital doesn't make it any different.
Your asset is worth whatever someone else is willing to pay for it.
I like looking at NFTs that have utility like Colosseum Cards. In this upcoming NFT game you can get Football players as NFTs and use them within the game. No difference the collecting and trading magic or baseball cards back in the day. The only difference with Colosseum Cards, since they are digital, they can be traded worldwide, used in the utility of the "game" and also you as the original opener of the NFT card can get passive income when those cards are ever traded again.
