Frankly, I have a few questions for you. Please don't get it wrong. Who are you and why should people buy your nfts? If you explain them well, maybe there is a chance that they will be sold. We don't know who you are. We don't know what he was doing and we don't know for what purpose he made these nfts. For all these reasons, frankly 10 ETH is a very bold price. I hope you can make the sale. But if you do what I said, it will be better for you.
Maybe he just wanted to sell his own craft as NFT images, but he probably didn't understand how to sell and set a price accordingly. sale.
Especially with the price of 10 ETH I think it is very expensive.
It is better if the price is corrected again so that it is really considered to be able to sell.
