What if an artist prices their NFT based on the current price of another artist’s creation?

Example: The cost of “Trade” is based on one (1) “One Year On Base — Still Day One” by @base. At time of minting, this was quite affordable. Of course, that’s subject to change.

Footnote: If you happen to already own the ERC20 token itself ($DAY1), you can use those. If you don’t, you can still use ETH but there are some additional transaction fees.
