Both nonfungible tokens (NFTs) and cryptocurrencies are relatively new forms of digital assets that are built on the blockchain, and both have been heralded for their potential to change concepts of ownership and finance respectively. However, there are also many concerns about the legitimacy and security of NFTs and cryptocurrencies.

Some also express concerns about their lack of regulation and potential role in crimes like money laundering.

This volume explains this complex topic and offers various viewpoints on the benefits and disadvantages of these assets.
