special kinds of virtual cryptocurrency tokens that utilizes the technology of blockchain to prove their owners

Yes, as soon as an nft is created the owner of that nft is recorded. It must be added that as soon as ownership is transferred too it is also recorded. This makes it very hard for a Duplication of the NFT.

NFTs are unique kind of tokens that are not interchangeable because they have special IDs assigned to each of them on the blockchain

Yes, this is rightly said . No matter the number of NFTs they are all unique in a way. Just like identical twins. We might see them to look alike in all aspects even their voice but there is always something different about them.

Payment can now be made through the wallet which was connected.

Yes, but I don’t know of other market places but on opensea the owner of the nft places the nft on the market and sets his price. He allocates a time frame for the nft to be on sale.

Whilst the market is on sale buyers are allowed to make their bids on the nft and during this period if the seller is okay with the highest bidder he can sell or wait till the time is up and then sale of the nft is made automatically to the highest bidder.

Note

For some reason I don’t seem to see your post when I click on the tag cryptoacademys2-w4 my suggestion is that you exchange it and make it the second tag to see if it will appear.
