Art as an asset class involves investing in artworks with the expectation that their value will appreciate over time. It encompasses various forms of visual arts, including paintings, sculptures, and photography. The field has evolved to include the use of technology, such as digital art and NFTs (non-fungible tokens), which have redefined ownership and value in the art market. Investors in art need to consider factors such as provenance, market trends, and the reputation of artists, as these can significantly affect the appreciation of the artwork's value.
