NFTs cannot be bought directly with „real money“ as they are based on blockchain technology and use so-called smart contracts that are executed on the blockchain to manage property rights and transactions. These blockchains are used with cryptocurrencies, such as Ethereum in our case, as a means of payment to settle transactions on the blockchain. Since the blockchain is independent of central financial institutions, the use of cryptocurrencies enables the direct and secure exchange of NFTs between buyers and sellers on a global scale without the involvement of third parties such as banks or payment processors. This technical approach provides a decentralized and efficient method to enable trading of NFTs and verify ownership rights.
