Well, we can see the funds on the wallet so you definitely have them but how much does the NFT cost, you're saying very low, I'm guessing less than 10$ and I imagine you're also taking the fees into consideration?
Where are you buying the NFT from? Magic eiden? Or are you using magic eiden as a wallet? If you're using multiple wallets but the same nft marketplace, the issue could be coming from the nft marketplace or the listing itself.
