OP maybe got inspired by that simple selfie that was made into NFT. https://www.businessinsider.com/indonesia-student-makes-a-million-selling-expressionless-selfies-as-nfts-2022-1

Nothing wrong to set a high price if OP is truly confident. OP can instead sell it in physical stores but the decision has been made.

Good luck to you OP. Hope someone is willing to pay that price.
