Hi, I am new in solidity and blockchain development
I have any questions about Crowdsale.
I am coding a new D-APP based on NFT, and I need to make them soldable inside my platform.
Crowdsale is for ERC-20, it could be used for ERC-721?
For now my smart contract make possibile create the new nft and store it.
User could sell the new Token.
How? With sell, or auction.
So they could set also a start time and end for auction.
When user buy a new NFT they could choose if let them in sold or not.
So the user could show in their account all NFT that own, without necessarily sold them.
Thank you so much for your help!
